This is going to get me into huge trouble, but:
To me, Star Wars is like Star Trek for the intellectually challenged
In more detail, what I ACTUALLY mean by that is not: stupid people watch Star Wars. What I mean is Star Wars is about the pretty pictures, big explosions, and drama. Star Trek is about philosophy, morality, and a vision of the future. I grew up with both, but never liked Star Wars, because it lacked the intelligence (which isn't necessarily a bad thing!) which I always felt Star Trek had. Star Wars is entertainment. Star Trek is a thought.
