Even if the plot was nothing new, I was completely satisfied because every other aspect was! The creativity of the concept, the level of intricacy in the details, and the outstandingly believable acting were all out of this world. I saw it twice in two days, and man, I would go see it again in a heartbeat!
This movie was very good, good acting, good story and plot - the only problem was with the animation. I haven't seen animation mixed with reality that horrible since "Who Framed Roger Rabit?". But ignoring that, the movie was excellent. It set up the future/past X-Men movies nicely, answered a lot of questions.
