Love them or hate them there are a lot of common tropes across the science fiction genre. What are some of your favorite and least favorite tropes?
I think it goes without saying that one of the least favorite tropes is Deux ex Machina.
I couldn't quite put my finger on it at first, but after watching the German TV show "Dark" I was utterly dissatisfied with it. The entire series up until the very last episode is about this inescapable time loop and alternative universes which is pretty cool while watching it, but then you get closer and closer to the end wondering how they are going to solve this impossible problem. Then surprise they just do it instantly in the last episode.
Another trope I am not very fond of is nanotechnology where there are trillions of tiny robots that can effectively act as magic. It just feels like a lazy way to write science fiction because you really want a fantasy.
A trope I do actually like despite how overdone it is, is the idea of a precursor or forerunner. It often brings to light the absolutely massive scale of the universe which I find fun to think about.
Also, every alien culture being uniform! Why does every Klingon have the same customs? Where are the equivalent of Russian Klingons and American Klingons and Chinese Klingons, etc?
While Planets of Hats definitely do exist, this one is more excusable for me because I think that it would be possible for the distinctions between individuals of an alien culture to be overwhelmed for the characters by the sheer unfamiliarity of the culture as a whole. And as far as national-scale distinctions, the characters may not interact with a very diverse range of people from the planet, maybe they have one or two crew members being from there, or maybe they visit once specific site on the planet rather than traveling widely across it.
I feel like you read my mind. I was just having this same thought the other day while driving. In the Star Trek universe humans are this very diverse group of people with all kinds of attributes and feelings and desires. Then you get to the Klingons or the Vulcans and somehow they are practically homogenous culturally, emotionally and in beliefs. I find that extremely unrealistic. There are different Klingon factions, but I can't even comprehend what their problems are with each other because they all believe the same things and have the same goals.
I still love Star Trek though. I just wish alien species were more than plot devices.
You might really like the book The Final Architecture. The author has very imaginative ideas on alien species that basically share nothing in common with humans biologically.
Blindsight has something like that too, the Aliens are completely different from humans in that book. And its available for free if you're interested..
I also like how the Three Body Problem solves this issue (are there spoiler tags on here? Would hate to spoil part of the plot).
I actually tried watching Battlestar Galactica awhile back, but the religious themes made me drop it far before the end. I'm glad I did if it turns even more into something I wouldn't enjoy.
I enjoy well done religious themes in sci fi and fantasy. It can either be completely goofy, and that's enjoyable in one way, or it can give a moment of "i wonder what the journey between what we have now and what they have looks like". Take for example Neon Genesis Evangelion; what the hell happened?
I actually dropped it a few episodes in due to the extreme shaky-cam space battle scenes. Every once in a while I'd reconsider watching it but the things I kept hearing didn't seem compelling, and then after I heard how it ended I was very glad I'd made the choice to stay away.
I guess this leads to another "trope" (I don't know if it's really a trope so much as it is bad planning) where a series is advertised as having a grand story arc or deep mystery that's unfolding as the series progresses. I've been burned by these so often that even though I love that sort of thing I now take it as a signal to avoid the series until it's well and truly finished so I can find out whether the showrunners really did have that or if they were just lying through their teeth to keep viewers engaged.
It's silly, but one of my favourite tropes is the obligatory Groundhog Day episode that usually happens when a series goes for long enough. Among all the great episodes of SG-1, Window of Opportunity is one of my favourites. I know Farscape and TNG had them as well.
And on the other hand the "Was the fantasy part of my life a dream" Psychiatric hospital episode.
That's always the episode that tells me the writers have run out of ideas and it's all downhill from there.
I fell in love with an book series called Expeditionary Force, the first book Columbus day hooked me. It's fun, it's interesting, and the writer does an amazing job making the technology being discuss sound realistic and not too far fetched.
With that being said, ExFor has ruined space battles for me in Sci-Fi and made me realize a trope we all just took for granted - The Dog Fighting type of close combat you see in ship to ship battles in Sci-Fi. There just isn't any way that would ever play out that way, instead combat would happen at ultra far ranges, so far apart, that railguns could be dodged, even lasers and other high energy beam weapons could be evaded just by moving out of the way as light crawls along. Combat would be about bracketing your target with fire, and ultra fast, high g smart missiles.
Space is so insanely large, that you'd never see dog fighting like in Star Wars.
Whenever "this universe" versus "that universe" comes up I always look at one thing for space battles. Effective Range.
Why would Mass Effect ships absolutely dick on Halo ships? Because their weapons fire ten times faster which means they can literally side step enemy rounds while landing them all. Day. Long.
Nothing else matters when you can just casually avoid everything your enemy throws at you.
My biggest peeve in this context is when the official "technical specs" for ships and other technologies have ludicrous numbers that make no sense with what we see on-screen. Star Wars is a big offender here, their ship weapons are often said to deliver shots with "kiloton" or "megaton" yields but when they actually show the shots hitting unshielded matter (such as a strafing run hitting the ground or shooting asteroids) there's just the equivalent of a few kilograms of TNT popping off. Yet people pull out those megaton numbers when "battleboarding" as if that's more relevant than what we actually see on screen.
They did a great job! It's one of the only other Sci-Fi stories I've seen that give a nod to the distances you'd encounter during ship to ship battles! I also loved the book series version of the Expanses take on ship to ship combat because they didn't have sci-fi ship shields. Going into combat meant, donning your vac-suit because the ship could very well get peppered with holes and lose pressure.
An attempt to explore how space combat would actually work at relativistic speeds is one of the few things I actually remember about the Lost Fleet series. The writing is wooden, the characters are one-dimensional and the plot is obvious, but it might be worth reading one just for the space battles.
Oh yes, I worked through the audio books for The Expanse last year, they did a fantastic job too! I also love that they address the idea of "on the float", no artificial gravity except spin or thrust gravity. The Expanse tackled a bunch of thing more relaistic then 99% of sci-fi does.
Give the Lost Fleet series by Jack Campbell a try too, lots of space battles explaining dealing with those exact problems.
Several discussions around orchestrating movements with groups of forces light-minutes apart, predicting actions of the enemy moving a significant fraction of light speed given your time-late view, and operating automated systems for maneuvering, targeting, and weapons control at those speeds.
A trope that's bothered me more and more over the years is planetary chauvinism. So many science fiction settings make the assumption that people will only ever live on planets - and usually specifically Earthlike planets - and anything else is just something for a mining ship to visit, when it's even thought of at all.
A somewhat related issue is the grand importance that Earth always seems to be given. I can understand it from the perspective of writing stuff for the general audience, it's super easy to make them care about whatever's going on by saying "oh no, Earth might be destroyed" but once we're a couple of centuries or millennia into being a spacefaring civilization with colonies all over the place Earth is going to be just one planet out of many. Star Trek is a particularly bad offender here since not only should there be plenty of human colonies just as big and important as Earth at this point but there are dozens of nonhuman Federation members too. The Federation didn't end when Vulcan got destroyed, it shouldn't end if Earth gets destroyed.
For the second concern i like the two Hainish Circle books i have read, "The dispossessed" and "The left hand of darkness". They mention that something like earth exists, but it's not even a plot point, it's just another planet. But then again these books are social commentar / thought experiment first and foremost, they just happen to be in a Sci-Fi setting.
The Culture does this best. Most Culture citizens live on orbital rings. You're allowed to move to a planet if you want, but it's not the norm and the Culture considers civilisations which rely on planets to be immature. They view it the same way as dependence on fossil fuels, it's destructive and unsustainable.
Oddly enough, an example from Star Wars of all places also pops to mind. The Ithorians had a culture that included deep reverence for the forests of their homeworld Ithor, and had a very communal society, so when they got technological they built huge "Herdships" that were basically flying cities. Initially they just hovered in the sky over their planet so as to not disturb the forests on the surface, but they eventually became spaceborne and became self-sufficient arks travelling the galaxy.
They still regularly returned to their homeworld, though. Until the Yuuzhan Vong destroyed it. The Herdships were unaffected, though and basically became nomads.
I recall a thread over on Reddit where I speculated at length about what the Star Wars galaxy would be like in the aftermath of the Rise of Skywalker and the fact that the tech now exists to build Star-Destroyer-sized planet-killer weapons and it apparently is pretty cheap to do so made me think that the galaxy might be forced to go post-planetary. A planet is basically indefensible but something like an Ithorian Herdship can just jump to hyperspace the moment a Xyston-class ship shows up in the neighborhood. It's hard to speculate with much confidence given the shoddy worldbuilding, though. Hyperspace tracking is apparently quite easy now too, so if someone really has it in for a particular Herdship it might still be screwed.
Necroposting to suggest the The Culture books by Ian M. Banks. The vast vast majority of people live on big space habitats like ring worlds, O'Neil cylinders, and Stanford Torii. Also some of the hugest ships carry basically a whole planet of people.
Obviously it has aged very poorly but Heinlein's Methusela's children series definitely goes all out against that trope. The main character spends paragraphs on how Earth did NOT age well.
I don't know how common the trope is, but since reading Accelerando i love the idea of extending your mind with computers. It starts with the MC sending AI-Agents to research tasks in the beginning of the book (something thats not that unrealistic nowadays), to most of a humans "thinking power" being outside their head.
"The precursor" is also always great. I loved the "broken earth" trilogy for that, most of what i remember from it is about finding out what the precursors did and how their artefacts worked.
What I dislike isn't really a trope, but it's when an author expects me to believe that future populations are stuck in the present cultural climate. A lot of old scifi books have aged really poorly because their authors could not imagine society moving forwards at all, so their societies of the future just seem dated. "The stars my destination" is like this imo.
I recently read the first Foundation novel as well as most of the second. Asimov was clearly not envisioning a more egalitarian future when he wrote about housewives destabilizing society when their appliances break and they can't get them fixed or replaced.
I honestly lost a lot of interest in continuing the series just because of that, but I also couldn't get attached to any of the characters since it zips around in history so quickly. I get that civilization itself is supposed to be a "character" of sorts, but that just doesn't appeal to me.
It's been a minute since I've read the Foundation series, but I didn't recall Asimov saying that society was destabilizing just due to appliances, but because they had forgotten how to repair/produce pretty much all modern technology (which of course the book being a product of its time, is all powered by mini nuclear reactors).
To your dislike that's what makes the Ancillary series pretty good is that there are a lot of weird new cultural norms spread throughout to give you the distinct feeling of a similar but separate human culture.
One of the big ones being that all characters are referred to as "she" but aren't all necessarily female. Plus lots of other little fun things like "lesser classes" being forced to wear gloves. It just goes the extra mile to make the universe feel a little more lived in.
When they constantly invent names for shit that already exists. It's OK here and there but you don't need to rename every little thing. It makes what's actually happening hard to follow.
Anathem did this very well; it was weird enough that it felt alien yet familiar enough I didn't really have to look anything up and it felt, well, real, without awkward pronunciation or phrasing. That and LOTR since it actually had a logical phonology and complete grammar. Helps that JRR was a linguist.
I think it goes without saying that one of the least favorite tropes is Deux ex Machina.
I couldn't quite put my finger on it at first, but after watching the German TV show "Dark" I was utterly dissatisfied with it. The entire series up until the very last episode is about this inescapable time loop and alternative universes which is pretty cool while watching it, but then you get closer and closer to the end wondering how they are going to solve this impossible problem. Then surprise they just do it instantly in the last episode.
Except they didn't just do it in a single episode. If you watch carefully, you would have realized that Adam & Claudia had been working their whole lives to get up to that point. None of it appeared out of nowhere, even with the fact that the climax happened in an instant.
Honestly this thread went through a lot of ones that I love/hate but one trope I can't get enough of is "the aliens are uncaring" like in Roadside picnic where they show up, throw some trash down on earth, and leave. They are never seen or heard from, they don't even bother with us in the book.
There is another series with a deus ex machina where some AIs evolve into godlike beings and then just mysteriously leave, but I forget the name of that one as well.
The Southern Reach trilogy (Annihilation, Authority, Acceptance) by Jeff Vandermeer kinda fits that bill as well. And most stories by Lovecraft of course.
It's a common theme where humans encounter some structure or evidence to suggest that some species or alien had existed millions or billions of years prior to humans. In Halo there are the forerunners that built the Halos for example. If you've ever played Mass Effect there are the mass relay's that humanity and other alien species discovered that connected large parts of the galaxy.
Before 343i and Frank "the terminal guy" O'conner was placed at the head of writing, the Forerunners were ancient humans as the original trilogy implies and directly states.
It was a cool twist that the ancients that left technology behind were actually humans that just forgot their own history due to the flood and Halo solution, then 343 just retconned the whole thing because they couldn't figure out how to make a new story that's actually compelling.
Well... Their actual story isn't compelling either but whatever.
Like the Forerunner civilization in Halo or the Precursor civilization in House of Suns. It's a long dead civilization that has tech abilities far beyond the current time period. So even though folks are zooming around in space ships they're intergalactic cavemen compares to those that came before.
This is maybe only tangentially related, but my most hated recent trend in genre fiction is "Your Fantasy story is actually Sci-Fi".
Numenara/The Ninth World is probably the most popular example (and I almost give it a pass for ingenuity), but it seems to be the go-to for trashy low-budget fantasy and webcomics; and it's also really popular in fan theories (Game of Thrones and AtlA being big examples). And there's always media that sort of straddles the line between the two (the new She-Ra: Princesses of Power show being an example; fantasy themes, sci-fi setting).
Of course, you could say the same thing about Star Wars. But I guess the difference, to me, is that Star Wars is unabashedly Sci-Fi. She-Ra tries to hide its Science Fiction behind of veneer of Princesses and pseudo-magical superpowers.
Another trope I am not very fond of is nanotechnology where there are trillions of tiny robots that can effectively act as magic. It just feels like a lazy way to write science fiction because you really want a fantasy.
