At the risk of stating the obvious, we're at the end of a decade. Time for lists! Here's the best movies I saw that were released from 2000 - 2009. Obviously, this shouldn't be taken as a definitive list. I reckon that if I had seen all the movies of the decade (or, you know, even a quarter of them), the composition would be altered, possibly significantly.
I made this list by going to the Wikipedia page for all movies of the decade and quickly scrolling through, jotting down favorites as I went. I wound up with a list of about 35, which I whittled down to here.
If you haven't seen some of these . . . well, you ought to.
