So, I just watched this...
Taking the X-Men lore out of the equation, and what we're left with is... Not much. It's a movie that draws not just far too much from X-Men: The Last Stand, but also from previous movies in this iteration of the X-Men. It feels like far too much of is it "been there, done that", even when it's being inconsistent with itself. And sure, while there are a couple of plot threads that actually seem interesting initially, they don't really go anywhere useful, if anywhere at all. The writing in general is just... Crap, if I'm being honest. The acting wasn't much better outside of McAvoy and Hoult, though Fassbender didn't really have a lot to do outside of what little they gave him. Pouty-Lips actually seemed okay as Cyclops as they gave him more to do, but he was, like most of them, the victim of bad writing. He's just less inconsistent than the others.
Sophie Turner... She tried. I'll give her that. Can't give her much more than that. Famke did a much better job of actually seeming tormented in Last Stand, imo.
Chastain... She's a good actress, but this role did absolutely nothing for her.
Otherwise, there were a couple of nice bits and pieces. The space-mission at the start is actually done well. Magneto and Jean duelling over the helicopter wasn't bad.
I will say this: The train sequence is one of the best action sequences in an X-Men movie. I mean, X-Men as a franchise isn't exactly overburdened with great action, but I really, really enjoyed it.
As an X-Men movie? It's not good. At all. Jennifer Lawrence's Mystique just... She gets in the way, and the movie is the poorer for it. It never recovers after she dies. Magneto gets crap henchmen too. A wasted Selene and hair-braid guy. Fantastic.
And why the **** does Storm, or anyone at the funeral, need a ****ing umbrella?
Cyclops with that f-bomb made me lol, as out of the blue as it was. That and him actually getting to do shit was a nice consolation for the fact that his VFX was horrible. Though what happened to him and Charles yelling at each other? That was in the trailer, but not in the movie... Stupid reshoots.
