22. The Artist
Great, great film, I loved it. The fact that it is a silent film has been called a gimmick, but I think it used it perfectly (there are a few wonderful scenes that only work because of "the gimmick").
Another important part is the music, since it's basically the only thing you hear and it's got one of the best soundtracks of the last year.
The film could have gone wrong very easily, but thankfully it didn't.
