I'm gonna assume for the sake of making my list that we're just doing 2000s as in 2000-2009, not 2000s as in 2000-present.
1- In the Mood for Love (2000)
2- There Will Be Blood (2007)
3- Spirited Away (2001)
4- Pan's Labyrinth (2006)
5- Children of Men (2006)
6- Wall-E (2008)
7- Speed Racer (2008)
8- Zodiac (2007)
9- No Country for Old Men (2007)
10- Paprika (2006)
I could have easily made a top 20, there are a lot of movies I love that didn't make the cut (The Prestige, my favorite 2000s Nolan movie, would have been 11, and Denis Villeneuve's Polytechnique would have been 12 probably, among many others).
