Top 20 Sci-Fi movies of the 2000s

My personal favorites of the 2000-2009 years. I'm a great SF fan, and wanted to make an all-time list but its too difficult for now, so I'm starting easy with this decade which is hardly the greatest for the genre. Note that I don't consider Donnie Darko, 28 Days Later and The Man From Earth as Sci-fi, but they would be high in my top 20 if I did.

The only films which would probably be in an all-time list of mine are the first two, the others I found good because they were either interesting/original, or simply fun/entertaining (which is the least I can hope for). I tried to list the movies in order of preference, but after the first ten it was difficult so don't consider it canon. The rest is more like honorable mentions. Thanks for your interest!
