Trekkies didn't like them for being too "Star Wars" of an approach to Star Trek, but people looking for a good sci-fi romp that just happens to have the Star Trek name on it liked them.

Basically "They put breasts and lesbians in Citizen Kane to keep modern audiences from falling asleep, now old people hate it."

Personally I was never that into Star Trek to begin with but I completely understand the need to "Star Wars it up" a little for a Modern Trek movie

I mean TOS is pretty good if you like old sci-fi (and I do) and quite dry if you don't (but that's just 60's media in general, the line between "Play" and "TV" was still being figured out), TNG is a mixed bag (When it's good it's an unforgettable must watch, DS9 is THE ABSOLUTE GOAT AND I WILL DO NOTHING BUT PRAISE IT! I'd worship the ground Armin Shimmerman walks on if I didn't think the Ferengi would charge to make me pay for the privilege, and Voyager and beyond (Shows currently running on Paramount+ included) you want nothing to do with. (Protip: Don't namedrop influential figures who are still alive as "people honored as gods in the future", you'll look really stupid when everyone's kissing Elon Musk's ass on your show as being the "Greatest Mind of his time" but then he buys twitter a week later and declares the Federation to be a Woke Mindvirus ran by socialist transgender money-stealers who do evil unAmerican things like try to feed the poor and judge people based on the content of their character instead of the color of their skin. Especially when it becomes common knowledge that he's the unsexy version of a himbo, and his staff constantly tries to keep him away from the engineers for fear his idiocy will waste their time and/or get them fired)

Voyager especially pisses me off, because how do you steal the premise of Red Dwarf (marooned in space with no way to get home, and getting into shenanigans hoping to find the way back), only decide not to make it a parody, and the result is, I still manage to take Dave Lister more seriously as a character than Janeway?

Lower Decks is okay when it's not being overly self-referential, when it isn't it's a worthy successor to Red Dwarf as far as "Comedy with relatable idiots IN SPACE!" goes, when it is it's like "Hey, remember on Star Trek when [CHARACTER] did [THING]?" and wondering why that in and of itself isn't a joke.
