You know, in my day the X-Men story in the comics was never about Mystique. She was a secondary character at best. Wolverine being big in the earlier films is ok with me, because he's been the most popular X-Man since the '70s, but Mystique's major role in the films is a bit weird. Jennifer's obvious talent and relatability make up for it a bit, but there's little of the comic book Mystique in Jennifer's portrayal.
