Interesting choices by many of you. I have to totally agree about Blade runner, Terminator, and the Alien movies. I think the production value of Aliens was overlooked. I don't remember seeing too many movies, prior to that, that used the military aspect so much and made it somewhat recognizable and believable.
I can't remember if it came after Star Wars or not, but Close Encounters might need to be included.
