Can't speak for everyone, but the reason that I care when one of my favorite IPs has a terrible movie, is because the terrible movie ensures that a good one will never be made.
They did a great job with Fallout, and now they are making a second season.
Then there's Borderlands.
I still haven't seen it, but I already know that the Borderlands movie I would have loved will never exist.
They generally don't work as movies because no one ever follows the story that's right in front of them. They always add some stupid artistic bullshit preference of their own which causes a huge disconnect from the source material.
I feel there's this trend where movie directors must and shall make their own story in whatever world is in front of them, instead of trying to make a movie that would fit in the game, or simply take the game's story and make a movie out of that.
It's why Lord of The Ring was so fucking good (Christopher Lee/Saruman read the books every year of his life, and corrected Peter Jackson whenever necessary), whereas Rings of Power is shit (I mean, a loving Orc family? What the FUCK have they been snorting!?). It's also why I'm hopeful to get something good out of Henry Cavill directing any 40k movie (that, or we're getting nothing, at best. At worst someone else takes over and we're getting female custodes for no good reason).
I don't buy that. It's possible but the producers always want to make it "theirs" and it's not. It'll never be theirs. The best they could do is just follow the source material as much as possible.
No one cares about your "quirky" changes. And this is quite evident in all the video game tv series that fail. Because the source material was basically thrown away completely. Because they think we'll gobble up anything just because of the name.
the Borderlands movie I would have loved will never exist.
For me it's Monster Hunter. I refuse to watch the one they made a few years ago. I wonder if there's a supercut of only scenes that feature the monsters. Or anything involving the Charge Blade.
After reading the synopsis, why tf did they have to make it an isekai?
I made it about as far into the Borderlands movie as i did with the monsterhunter movie, bailing after about a 3rd of the film.
Not really super popular take, but the sexual politics (as in the way the story treated women) in both were something I struggled to get past. Plus they were both goofy and not in a very fun way. I have very similar feelings about the fallout show lol, but glad you enjoyed it.
But i think i teenager might have liked borderlands
Just reiterating what others have said but... if you have an IP you like and want more of it in the future (regardless of medium!) then its success in any other medium will likely impact whether or not you get more.
Unfortunately, we live in a world where:
Money matters more to most IP holders than the IP itself
New IP is seen as risky
Those in charge don't have to take responsibility for their failures
If there is a commercial failure of an IP, there is a good chance that its failure will be seen as the IP generally failing or falling out of poluarity instead of the failure to best utilize the IP that likely occurred. As a result, priorities will often shift away from the IP to something else in all mediums (ex. ASOIAF/GOT). Unless the IP is absolutely gangbusters in all other mediums, it will suffer. Similarly, success will likely lead to more utilization of the IP in any medium.
It's unlikely that the IP owner will sell or license the IP in the near future because at one point it was popular and new IP is hard to make. It would be better to hoard IP and maybe try again in a decade when they need a trick up their sleeve. Plus, another failure might damage the IP even more.
Admittedly, I'm not attached to any brands or IP in particular and so I'm not invested really. I just makes me a little sad when some IP I thought well of has this happen... or when the person who benefits from the IP turns out to be a person I'd rather not give money to. Occasionally I'll ponder what might have been if things had gone differently and feel a little bad.

For example, when EA released Tiberian Twilight and it was absolutely awful and didn't sell, they said that people just didn't want RTS games anymore and shelved the entire C&C franchise. That was fourteen years ago and we haven't had a new C&C since then that wasn't mobile shovelware.
I'm not like, attending a protest rally or anything. I think it's perfectly fine to spend literally 7 minutes of my day telling people that this movie is shit.
You "no one should ever express disagreement with anything" people need to chill.
