Best Movies of the Decade (2000-2009)

With only two weeks left in this decade, I was wondering what everyone's favourite movies are from the past ten years.

Any hidden gems that didn't find success in theatres? Any movies that you can watch over and over again and it never gets old? They can be foreign or critically acclaimed or just something you like and no one else seems to "get it".

Here's my list:

The Dark Knight
Donnie Darko
Wall-E
Kill Bill Vol 1.
Lord of the Rings Trilogy (I know I cheated...but I can't separate the three...I consider it now a long almost 10 hour movie.)
Polar Express (This grows on me more and more every Christmas.)
Juno
Almost Famous

So how about yours?
