No, I'm going to focus on something much narrower about this movie: its depiction of Angel Salvadore, a relatively minor character in the comics and a supporting character in the film.
I was very surprised to see her in this movie, because 1) she's a very recent character, and wouldn't really belong in a story about the relationship between Professor X and Magneto as young men (not that that's stopped any of the previous movies, where characters from different generations of X-Men have always been thrown together willy-nilly), 2) none of the other characters*, or plotlines, she's involved with make any appearance in this movie, and 3) she's very unphotogenic. She's half-girl, half-fly, and her offensive weapon is super-acidic barf.
Here's what she looks like using that power in the comics:Gross, isn't it?
That's why I was so surprised, before seeing the movie, when I read that she'd be in it. Female characters in movies, especially in comic-book movies, action movies and other movies aimed at a teenage-boy audience, are primarily there as eye candy; when they're allowed to do cool stuff and look pretty it practically counts as a feminist victory, but the look-pretty requirement is not negotiable.
And there's no way to make disgusting green barf look pretty; hence my surprise.
It turns out I underestimated Hollywood's ability to pretty almost anything up: I can't find any video on YouTube that includes this, but when the younger mutants are all showing each other their powers and picking out their X-Men codenames, Angel demonstrates something that looks nothing at all like what's pictured above. She strikes a pose, puckers her lips and releases a smoldering fireball about the size of a Ping-Pong ball, which arcs prettily through the air and lands on the statue's head, where it begins to corrode the metal**.
She uses this power again in a battle near the end of the movie; she's flying through the air breathing fire like a dragon. Less ladylike, but still not gross.
*Except Professor X, obviously, and also Magneto. Though the extent to which Magneto was actually involved in the events of Planet X are debatable ... the character who tried to suborn the Xavier School's "special class" into a reconstituted Brotherhood of Evil Mutants and conquer the world was apparently later revealed to be Not Really Magneto At All. I haven't read the comic where that gets hashed out, though, so I am quite fuzzy on the details. I just know that the whole question of "Does Planet X Count as a 'Magneto Story' or not is very contentious --- see the comment thread on this post.
**For whatever reason, the fireball-spewing part of Angel's power demonstration is missing from all the clips I can find.
