[SPOILERS HERE] Developing a character is not only showing his/her background. We already know where she came from (X3 - ugh!), there was no need to show it again. She starts as an "outcast" in a whole school of "outcasts"; she goes from being afraid of herself and her growing powers to being the one who ends up…

The movie is great - especially if you're an X-Men fan. It is, indeed, a lot different than First Class and Days of Future Past, but still it's not a movie about nonsensical action. It has a point and it definitely has memorable moments. Sophie Turner is great as Jean Grey, she really delivers it; Tye Sheridan is the…

There are others far more positive than this. Including one that reads: "'X-Men: Apocalypse' [is] a thinking person’s action movie." And that's true.

"Undeveloped characters"? Well, I think we haven't watched the same movie then.

No, it's not. It's actually about presenting you the "new" X-Men team. Charles/Erik/Raven have their story "concluded", but the main point of the move is to show the young mutants and how they become a team (the X-Men).

I have just watched the movie and it's great. Yes, a lot of CGI but still a movie about characters. A lot about characters, actually. The tone is really different from First Class and Days of Future Past, indeed, but this is not a movie about nonsense action (like Transformers).

A psychic battle is not a "dream"… Xavier wasn't "dreaming" about it. It was really happening, inside his mind. So much so that he would have been physically killed if someone else (no spoilers) wouldn't have interfered.
