45. The Hunger Games
It's a very well done adaption of the book. They let go of the first person narration of the book (which would have resulted in a lot of voice over), but replaced them with things like the two commentators during the Games, which fit great. The casting (and acting) was very good, as was the desing of the world (maybe District 13 didn't seem as poor as it was in the book, but that's always going to happen in films where you can't have all your actors and extras starve for several weeks just to look the part).
If I had one complain, I'd be the camera work: I liked the shaky-cam during the fight scenes, but in some quieter moments it would have been nice not to shake and move the camera the whole time and insert a cut every second.
