X-Men First Class
If you haven't seen it, make a plan to do so.
If you weren't planning on seeing it after the tripe that was X3 & X-men Origins, don't let this epic movie pay for this sins of what came before.
Easily ones of the best Super Hero movies since Watchmen and The Dark Knight and while its not entirely on The Dark Knights level its gets close.
Next up Green Lantern & Capitan America before the long wait to next years The Dark Knight Rises & The Avengers.
