I've watched a movie every week since 2010 started and thusfar, the only one to impress me beyond belief was Harry Potter.
I suppose Fast Five and X-Men are up there too. :P
EDIT: OH! And 50/50!!!
2012 looks promising though. With The Dark Knight, The Hunger Games, a possible new X-Men: Origins movie.
GAHH! Contagion killed me!!! It was so boring and redundant. That entire movie was just too stretched out. The entire thing can be summarized in 10 seconds.
This year was very lacklustre for movies, but also some of my faves of all time were released.
The best movies released this year for me are HP8, Bridesmaids, and Just Go With. There might be a few others I missed, but other than that, I never wanted to go the movies, nothing intrigued me. Especially nearing the end of the year.
