I have no problem w/the move to the sixties..that is where the X-men series began and its themes originated from. It's renewed my interest in this film. I also like the idea of using sixties-style Bond tech. I do agree that it causes continuity problems, like Cyke's brother, but some like Emma Frost don't really matter in the long run..the girl from 'Wolverine' could just be some random girl who has emerald-skin named Emma, while the one in 'First class' could be the Hellfire version with a more Emma-like personality..it's not too much of a problem to me since in each of the first 3 films we had a different girl playing Kitty Pryde. I never found the Emma in 'Origins' to be the actual Emma anyway. Guys like Beast you don't have to worry about too much since in the 3rd film he didn't really have an established age. Personally I'm excited to see it using the issues of its time, like the red scare and Civil Rights movement, where the X-men work so well.
