All the X-Movies have taken lots of liberties with the extent to which characters reflect their comic incarnations, though. Apart from Magneto, I can't think of anyone from First Class that really channeled their comic character very well. Beast was probably closest, but even that wasn't very close (he was too mousy, didn't come across as witty and smart enough with his language, and didn't really move the way that I always imagined he would). Prof. X, Sebastian Shaw, White Queen, Banshee, and Havok were hardly recognizable to me. Stewart's Prof. X, Jean Gray, and Jackman's Wolverine were pretty damn close to their comic incarnations in X2 IMO, if that's your criteria for enjoying the films. I think Storm and Nightcrawler also had the potential to grow into their comic counterparts if the series had taken the right track.
