Green Wing will be right up your alley if you're a fan of all these shows! It's a sitcom/drama set in a hospital but it's not a medical drama. It's entirely character driven, very absurd in its humour, and almost like a sketch show at times with how some of its scenes play out. It's tied with Black Books for my favourite comedy series (and Tamsin Greig stars in both, too).
Not that obscure, but my favorite show of all time is Babylon 5. It may not be visually impressive, but the writing is excellent, the story is compelling, and the characters are richly developed and likeable.
The Adventures of Brisco County Jr. is a western starring Bruce Campbell. It's a wonderful blend of western tropes, scifi elements, and humor. But what I love most of all is the optimism. It's from the 1990s and is set in the 1890s, and a major theme is looking to the future, towards a new century full of amazing advancements. It's full of anachronistic inventions of the week, and excitement for the possibilities that they represent. It's beaming with hope for the future, something which was common at the time but now feels quaint and nostalgic. "You remember when we thought things would get better? Those were the days."
Mine is Babylon Berlin. For fans of Peaky Blinders, Boardwalk Empire, Warrior, Man in the High Castle.
It's a neo-noir thriller series set at the tail end of the Weimar Republic. It deals with the emergence of the Nazis and the breakdown of Weimar democracy. There are 4 seasons out right now.
Killjoys - Space bounty hunters show with a very similar vibe to Firefly. 5 seasons of 10 episode each, and has a proper conclusion.
Slow Horses - MI5 rejects and screw ups are assigned to Slough House, run by Jackson Lamb played by Gary Oldman.
Misfits - Teens doing community service are caught in a freak storm that gives them superpowers.
Dirk Gently's Holistic Detective Agency. It requires you to watch till the end to get the full payoff and everything clicks together and makes sense but I thought it was fun and out there.
Two more since we're bringing up 90s shows: Space: Above & Beyond and Earth 2.
The first is about space Marines fighting an alien enemy. It's gritty and dark with a pretty well fleshed-out universe complete with an AI rebellion, cloned soldiers, and awesome and pretty realistic space combat. CGI isn't bad for the 90s either.
The second is about a group of colonists who are trying to find a new world since living on space stations is making their kids sick. They crash land due to sabotage, and find that the planet is home to two sentient species and a smattering of prisoners and former colonists. The cast includes Tim Curry and Clancy Brown before he was Mr. Krabs.
Charlie Jade - sci-fi filmed in Sputh Africa for a Canadian Netflix-type network. Three worlds, all intertwined.
Letterkenny - just watch the season 1 Cold Open. If you die laughing, the show’s for you.
MXC - take the old Japanese game show “Takeshi’s Castle”, and hire some of the Groundlings improv comedy troupe to “aggressively redub” it. Offensive and hysterical. If you giggle at the two Japanese hosts being named “Kenny Blankenship and Vic Romano”, or that the guy in the military uniform is Captain Tennille, this is for you
The Chronicle - early Sci-fi channel about an Enquirer-type tabloid that IS telling the truth, and Bat Boy works there.
The Prisoner. One of the original Cult Tv shows. Still holds up, discussing the surveillance state and personal privacy and choice and more.
I would say that my favourite tv shows are probably just as known as my least favorite ones, but I'm not a very popular person so not many people have much reason to know about either.
