X-Men: First Class is a good movie. If you like X-Men, you will like this movie cause it kind of shows how things got started. There was action, adventure, some comedy, and awesomeness. The only sucky thing was that there wasn't an extra clip at the end of the credits. :( So don't stay after the credits.
The movie starts out showing when Erik/Magneto (Michael Fassbender) and Charles/Professor X (James McAvoy) are young in 1944. Erik is in a Nazi concentration camp where Sebastian Shaw (Kevin Bacon) is working on genes and mutants. Charles is in his house and finds young Raven/Mystique (Jennifer Lawerence) who is trying to steal food. Charles tells her she can live with him and so she kind of becomes his sister. The movie then flashes to the 1960's. Erik is looking for revenge against Shaw and Charles is going to become a professor of genetics. Moira MacTaggert (Rose Byrne) is trying to investigate mutants and seeks out the help of Charles. Charles and Raven go with Moira to the CIA where they meet people who are helping mutants and they meet Hank McCoy/Beast. There they recruit more mutants to their team. They find out that Shaw is trying to start a new world war and they have to stop him.
This movie was pretty sweet action. The story is different from the comics, but unless you are a comic book nerd, I don't think you will mind because the movie is pretty darn cool. I might be seeing it again tonight. :) I recommend that you go to the movie if you like superheroes and X-Men and stuff like that. Once again though, there is no extra clip at the end and Stan Lee isn't in this movie.
