The question, though, isn't "What's your favorite" or even "Which one influenced/predicted the future the most". It includes the phrase, "as far as setting the agenda for other sci fi movies."

On that parameter, I would have to go with Star Wars, hands down.

As science fiction goes, it's not to be taken too seriously. As a piece of cinematic art that influences those who come after, it has never had an equal. George Lucas' vision was WAY ahead of it's time. The actors were running around with green screens, mostly thinking, "I can't believe I got dumped into this stupid thing." Nobody but George understood what was being made. And then it hit, and the world of science fiction movies has never been the same since.

(With all that said, Blade Runner rules!) smile
