I just re-watched First Class this past weekend as well after seeing it in the theaters earlier this summer. Just a really well made movie overall. When it was announced, and the character lineup was revealed, I really had reservations and wasn't sure how much I cared to see it. But, although I still would have liked to see the comics version First Class characters included, I was really impressed with how good it was. Magneto in particular steals the show I think. The continuity is all out of whack with the other movies, but I sort of take it as a reboot anyways and hope they continue on with this cast/world (and eventually include some of the classics like Cyclops, Jean Grey, etc.)
