Before Charles Xavier and Erik Lensherr took the names Professor X and Magneto, they were two young men discovering their powers for the first time. Before they were arch-enemies, they were closest of friends, working together with other mutants (some familiar, some new), to stop the greatest threat the world has ever known.

With a strong script, stylish direction, and powerful performances from its well-rounded cast, X-Men: First Class is a welcome return to form for the franchise.

'X-Men: First Class' is lauded for its strong performances by James McAvoy and Michael Fassbender, and for revitalizing the franchise. Themes include the origin stories of Professor X and Magneto, mutant identity, and historical events. Criticisms involve deviations from comic storylines, inconsistent character ages, and script weaknesses. Despite these, many appreciate the action sequences, visual effects, and future series potential.
