okay, yes, so maybe in this new timeline jean grey caused her parents to get into a horrible car accident, but in the old timeline she was Smug™ so who can say which was the worse version of events
so one of the realities of having a franchise that lasts twenty years over the course of thirteen movies (and two TV series!) is that occasionally you're going to have some shit films. this isn't necessarily a death knell or anything, hell, the X-Men series itself managed to survive the double whammy of The Last Stand and then Origins: Wolverine. But with those films (and X-Men: Apocalypse), there still manages to be something fun about them, whether it's spectacle or some kind of goofy bad-movie-schlock factor.
so dark phoenix sucks, right
and like it sucks in particularly unfortunate ways. it's not like fun schlocky badness like Origins: Wolverine or have the absurd spectacle of something like Apocalypse. it's pretty blatant that almost none of the actors really want to be here and there's a lot of incredible phoned in performances, with one in particular that i'll get to when it becomes relevant. i think the only person who actually gave a shit in this movie is fichael massbender just judging by performance (but then Magneto's always been the most interesting character in any of these films).
one has to wonder how much of the "we really wish we weren't here right now" energy was because of the impending announcement of 21st century fox's acquisition by disney, which was announced 2 months after initial filming wrapped. they almost certainly were aware of the possibility that it was happening, right? not to mention the plot threads they ended up needing to cut out of this and The New Mutants (which had its own wacky brand of behind the scenes issues) when it became clear that the story wouldn't be continuing. Remember all the setup the Essex Corporation got over the last few movies? almost kind of bums me out that we'll never find out how they planned to justify a goofy codename like "Mister Sinister" in this franchise.
oh, and shoutout to Fox being like "we don't NEED the X-Men branding for our movie to be successful, we're just gonna call it DARK PHOENIX" only for every single home release to be updated to "X-Men: Dark Phoenix." Way to commit to the bit you guys.
