Can you imagine, for you youngins, the thrill of seeing stuff like that on the screen? I mean, this was no Star Trek combat, but actual space fighters. Real alien-looking aliens that only had a vague humanoid shape (as opposed to blue face-paint and a white wig with antenna). Weapons that didn't make the pew pew laser sound...
Just imagine what people used to the movies from then must have thought.
It would be like comparing Halo 3 to Super Mario from the Nintendo!
