I'm ranking them on entertainment value, not artistic quality... 
1. TRANSFORMERS 3: sue me, I like robots fighting :-p
2. HARRY POTTER 8: defintely brought a tear to my eye. a great finish, it's just when I know the events so well, it's hard to be excited about it as a movie.
3. THOR: much better than I thought it would be.
4. KUNG FU PANDA 2: just as good as the original.
5. MISSION IMPOSSIBLE 4: incredible action scenes!
6. X-MEN FIRST CLASS: pleasantly entertaining
7. FAST FIVE: I liked how this franchise evolved, this is the best one yet.
8. CAPTAIN AMERICA
9, TINTIN: if only there had been a few more amazing set pieces.
10. SHERLOCK HOLMES 2: no complaints. loved Moriarty.
RUNNERS UP:
RANGO (best CGI ever), SUCKER PUNCH (disappointing), PIRATES 4 (disappointing), HANGOVER 2, SUPER 8, GREEN LANTERN (VERY disappointing I love the comic!), COWBOYS & ALIENS, RISE PLANET APES, ATTACK THE BLOCK (best movie nobody's ever heard of), PUSS IN BOOTS, HAPPY FEET 2, MUPPETS
