I will give this film its due. It is probably the best shot out of all the x-men films out there. Visually, it was amazing to watch.
Storywise...it was bullshit.
I mean, "there are no more x-men because Xavier had a seizure" is...well, it's a fucking insult. Especially after Days of Future Past did so much to give us a Happy Future after all the bullshit that had gone down in X-3 and nearly killed the franchise. I mean, you're telling me that some of the greatest scientific minds out there, like Beast...didn't notice a problem during routine physicals, and a school that regularly dealt with out of control mutant powers via the students wouldn't have defenses set up for EXACTLY the kind of situation that happened? Fucking bullshit.
Also, the whole "this damn adamantium is killing my healing factor" thing. No, clearly, not the case. Because he'd had it for what, 40-60 years with no side effects? I might have bought the healing factor dying off due to the massive trauma of what Xavier's mind farts had done overloading Logan's body (since it was enough to kill an entire school of mutants while Jean "Muh Phenux" Grey was in house, and again, how come she couldn't do shit?). But nooooo.
Hell, I would have accepted the whole "gene therapy that destroyed mutation" as an argument for why logan lost his healing factor and xavier when spastic, but they didn't even give that much.
The whole "weapon x" project struck me as stupid too. I mean, X-23 is about 12 in the film? Charles only had his fart a year or two before the film started...so Xavier, the world's most powerful telepath, who could have been searching weekly for new mutants since the "vanishing" never picked up a dozen mutants all i the same place? Or again, the X-men, a group built to find and take out threats to mutants, with geniuses on the team, never, ever, ever...figured out the cause even though, logically, they should have been searching day and night for why it happened?
