Imagine making a movie that has such big stakes, but make it so nobody cares about any of the characters.

Jean Grey - Yawn, [spoiler] she struggled with controlling her powers, controlling her emotions. Some part understandable but I felt no emotion. [/spoiler]
Professor X - [spoiler] Acts like a Villain for the first half of the film.[/spoiler]
Mystique - Shouldn't have hired Jennifer Lawrence, she couldn't handle the make-up. [spoiler]Attempts a death scene but leaves no emotional impact.[/spoiler]
Quicksilver - Has some of the most iconic scenes in comic book films and they don't give him his scene. [spoiler]Gets injured early on and just disappears until the end of the film.[/spoiler]
Storm - Was just there to do damage.
Beast - The only character with correct motivation and you somewhat understand why he feels the way he does. Just feels like bad casting personally. Hoult is just too youthful and skinny for beast.
Cyclops - His character is just completely centred around Jean. Feels like we never get to see just Scott.
Nightcrawler - [spoiler]Where does this come from, he just become a murdering psycho and the build up just seems too out of character for him.[/spoiler]
Magneto - Probably the best performance, [spoiler] character flipped sides very easily considering his motivation for wanted to kill Jean.[/spoiler]
Jennifer Chastain/[spoiler]Aliens[/spoiler] - Why, what, who, what, why.

Good scene - [spoiler]Using their power to fight over control of the helicopter[/spoiler]
Bad Scene - [spoiler]Every single one with Jennifer Lawrence[/spoiler]
