I saw the film today and was totally impressed. One of the best comic book adaptations ever. It tells the story how the X-Men came to be. How Charles Xavier met Magneto. How the Hellfire Club tried to start World War III. Eric Fastbender as Magneto was tremendous. He was arguably the hero of the film. A very cool anti-hero. You have no problem sympathizing with him as he hunts down the evil nazi scientist (Sebastian Shaw) who experimented on him as a child. While they took some liberties with the X-Men origin, they actually improved upon it and stayed very faithful to it for the most part.
It was thoroughly enjoyable.
