Ok just finished the movie.
Overall I think the concept was good, but it really suffered badly from being merged into one movie, there were too much to tell and too many characters. It also created plotholes.
Other than Xavier(which also could be expanded a bit more), Magneto and everyone else got little further development. It really tires me to bring Magneto again to fight the X-Men, there were very little build up on these characters, both old and new.
Sophie Turner was ok on her performance, the plot could have been longer to stretch the development.
Glad to see Mystique die, they made her a hero simply because of her actress.
Why would Magneto think there is a chance he could kill Jean after what happened in Apocalypse?
The villains were the biggest problem of this movie, they are just purely bland and acted unnecessarily cruel.
Why did they attack the train when they are shapeshifters and have FBI members who could even get into the White House? They could have just wait and sneak in.
Why didn't Jessica Chastian's villain just absorb the Phoenix power from Jean right way when she first met her?
I'm sure if there have been 2 movies most of the problem would have been solved.
