Ever since I was a kid Science Fiction movies have always amazed me and entertained me.  At first they were just cool because they had spaceships, alien sidekicks, and laser guns.  But as I got older and watched more and more SciFi movies, there were certain ideas of humanity which remained constant.  It didn't matter how far away from Earth you were, or even how different that Earth compares to our own, the spirit of humanity never changed.
