Just a note on inconsistency, with the comics.
Emma Frost's Crystal form was a secondary ability added later in her characterization in the comics. It definitely was not at either point in time in Origins or First Class. It was after the Genosha masacre it happened.
That ability was given to her by Cassandra Nova or more Nova is able to activate
latent mutant abilities.

Yeah, I thought that. I guess they figured the other helmets in X1-3 received so much hate, that they would "give" fans what they wanted and try to go closer to the comics. However, they could have done better. They should have had whomever designed the Thor movie helmets design Magneto's.
