Bladerunner, because any movie based on a book by PKD is awesome. Well, except for all those other movies that were just okay. And I guess Bladerunner didn't really follow Do Androids Dream of Robotic Sheep very well anyway....
Well it was a great movie nonetheless. Moon was also a great movie.
My favorite Sci-Fi movie, that hasn't been mentioned yet would probably have to be The island. I haven't seen it in a while but I remember it quite well. It isn't well known where I live but I liked it. Not very action packed as I remember, I'm probably wrong though.
That was the weirdest movie ever. I still don't understand it. Hal is the only good part in my opinion.
You have to watch 2010 to help you understand it or read the books. (I read all of them 2001, 2010, 2061, 3001 and they were all excellent). I like the Fifth Element with Bruce Willis, The Chronicles of Riddick, Pitch Black (which was before the Chronicles...), Stargate, Total Recall with Arnold Schwarzenegger, Alien, Star Wars (all of them), Star Trek (all the movies and the new one is great), 2001 and 2010, Starship Troopers (all of them), Terminator (all the movies). That's all I can remember right now.

your right, its about clones that exist only so you can live longer if you are ill. two clones flee from the island and get hunted because this island is a secret.
