1. The Bourne Ultimatum - Can't describe this, just great. The whole series, in my opinion, is better than LotR.
2. Zodiac - Good mystery, kind of like CSI, 3 hours long, and based on a true story.
3. 300 - Great cinematography, and like Sin City, does a good job on capturing the comic book feel.
Honorable mention: TMNT - Not as good as the legendary animated series (or the previous movies) but it's TMNT after more than 10 years, so it deserves a spot.
Bourne wasn't on my list at first, because it wasn't on BaB's list. After I made my list, I remembered the movie, and the others had to slide down..
Edit: There was also Pan's Labyrinth. I liked it, and it may just slip in at no.3.. Or maybe not.. I can't decide..
