The black guy always dies
Even when there are blue and red white characters. Goddammit Hollywood the cute digs about mutant=gay are cute, but WHY KILL THE BLACK CHARACTER? RIGHT AFTER REFERRING TO SLAVERY? Edit: after some thought, I've concluded they should've killed Havoc instead. Isn't he Scott's YOUNGER brother anyway? He's hardly plot-central.
Emma Frost in bed-bondage is hot but wtf? Also Angel must've been disappointed and a half with the Hellfire Club's uniform for its women members. (Also, black male character: cab driver, dies; black female character: exotic dancer, selfishly changes sides. Which she is, herself, within her rights to do--but COME ON, writers.)
I am still trying to figure out Magneto/Mystique. They're in different movies. He's doing the "Is it ok to kill people who hate you?" character arc and she's doing the "Different can be beautiful!" character arc. For their relationship to work, she HAS to decide that it's ok to kill in self-defense--especially since we know she's also going to hook up with Azazel the industrial blender. I don't think the movie's comfortable with the "Accepting yourself means killing people who hate you!" implications of drawing out Mystique's respect for Magneto.
That said... that's later. When they hook up, it's not development for him at all. There's a pretty naked lady in his bed, and he doesn't mind helping her learn to accept herself. I see no signs that he's losing respect for her, or objectifying her, or anything, so only her apparent youth in her barely-18 blonde form (HOW old are she and Xavier supposed to be?) is especially disturbing.
In the three months after the end of this movie, Mystique is going to age about ten years, I guess is my conclusion.
And that's a really cool story.
Also, lots of stuff blew up. I liked it.
