Disappointment sometimes seems the natural state of mind for science-fiction fans, but it's because we have so much hope. We raise our hopes again and again, only to suffer crushing disappointment. Here are the 10 worst letdowns of the 2000s.
Note: I'm not including the Star Wars prequels here, because the big letdown was The Phantom Menace in 1999. After that, the other two movies couldn't really be letdowns.
