It was a really great decade of films. Here are 31 from me (ones that correspond with yours in bold.) Why 31? Because I can't cut any more from this list - even just one to make it 30. I like these films too much :
Dancer in the Dark (2000)
Unbreakable (2000)
The Ring (2002)
Training Day (2001)
Oldboy (2005)
In Bruges (2008)
Requiem for a Dream (2000)
Kill Bill Vol. 1 (2003)
Kill Bill Vol. 2 (2004)
The Pianist (2002)
Adaptation (2002)
The Royal Tenenbaums (2002)
Broken Flowers (2005)
Million Dollar Baby (2004)
Zodiac (2007)
Napoleon Dynamite (2004)
Little Miss Sunshine (2006)
Inglourious Basterds (2009)
Memento (2000)
Borat (2006)
There Will Be Blood (2007)
Amélie (2001)
The Departed (2006)
Juno (2007)
Casino Royale (2006)
Brokeback Mountain (2005)
Shaun of the Dead (2004)
No Country For Old Men (2007)
Eternal Sunshine of the Spotless Mind (2004)
Lost in Translation (2003)
The Dark Knight (2008)
These are the ones that came to mind straight away. I'm sure if I were thinking it over and adding titles over time there'd be some I've missed.
Others from your list that I really like were Zombieland, Tropic Thunder, The Hangover, Final Destination, Taken, Hot Fuzz, The Lord of the Rings: Return of the King, The Simpsons Movie, War of the Worlds, The Lord of the Rings: The Two Towers, The Lord of the Rings: The Fellowship of the Ring, King Kong, Batman Begins and American Psycho.
Superbad, Pineapple Express, and all the Bourne movies are movies I'm going to get around to watching pretty soon. I really enjoy watching any Friday the 13th or Final Destination movie - which are guilty pleasures for me.
