it's actually about as perfect as Sci Fi can get on film. I only forward to you the opinions of some respected Sci Fi writers.
A mentor of mine back in college (sci fi author), feels that it stands next to 2001 as the best examples of Sci Fi film.
Meh, I just didn't enjoy it. Was pretty boring to me. I don't get why everyone loves it so much.
And yes, I have seen The Thirteenth Floor and liked it.
