X-Men: Apocalypse

Similar. In principle, it's a decent movie, and I must admit that I enjoy the Marvel storylines about mutants much more than all those Avengers stories. The world seems more alive, more dynamic... The characters are interesting and not so one-dimensional (even when the Avengers behave inappropriately or atypically, when they try to show some internal struggles, it looks extremely artificial, as if they instantly become absolute idiots for a while). Here, the setting itself is such that the characters' actions and conflicts make sense. Of course, there are complaints about the movie, and the speed that Ar mentioned is particularly noticeable. But overall – 7/10
Now, spoilers ahead

But the worst thing is how poorly the motivations of the characters who joined the main villain are portrayed, although Magneto is still portrayed relatively well.

As I understand it, the main motivation is some kind of mystical experience, when Apocalypse gives his servants power. He somehow integrates himself into them and so on... It looks like a reference to a mystical experience; the religious Polish Magneto almost takes Apocalypse seriously as the one he is used to praying to. So... I think this moment is quite normal, perhaps a little exaggerated, but not too much.

except that the flaws in terms of mechanics don't compensate for it

Heh, yes, Quicksilver saves everyone from trouble at hypersonic speed and manages not to break their spines )) Well, there are many such things...
P.S. I didn't see the post-credits scene; I waited quite a while for the credits to end or at least be interrupted, but my patience is not limitless.
