Oldies, but goldies are always better in my opinion. Graphics alone doesn't make a movie great.
Just to name a few good ones I've seen growing up.
Older Star Trek movies (usually people like the even numbered ones better, just FYI)
Stargate
Enemy Mine
The Fifth Element
I, Robot
Galaxy Quest
War Games
Wing Commander
Earth Girls are Easy
Heavy Metal
Explorers
Waterworld
Tron/Tron Legacy
Hitchhiker's guide to a galaxy (BBC is more complete, remake only covered half the book)
The Last Starfighter
Serenity
My Stepmother is an Alien
Starship Torrpers
Planet of the Apes
Tank Girl
