No, I know what you mean. And yeah, stuff like Alien and Blade Runner wouldn't have made it if it hadn't been for Star Wars. It really opened the floodgates. Unfortunately, a lot of junk came out as well...which isn't really surprising, since keeping in the junk is what floodgates are for, right?
EDIT: And really, all I wanted to do was advertise Escape from Galaxy 3, one of the finest space operas ever to come out of Italy in 1981.
