Here's the thing...I don't believe he does.
Did he originally create Star Wars? Yes, he absolutely did. But if it weren't for the fans, he wouldn't be who he is today. He wouldn't be a household name, recognizable throughout the world. Hell, if it weren't for the fans who loved "Star Wars" before it became "A New Hope," we would have that one single Star Wars movie. Just the one. The original Star Wars. Initially, he NEVER planned on making it a trilogy.
Since we, the fans, put him where he is today, he in a way OWES us. He owes us for loving the first Star Wars movie, loving it enough that it become a cultural phenomenon that continues to be absolutely beloved even today. Should he listen to every fan boy that comes along? Absolutely not. But we, as diehard fans of the series, *deserved* a Star Wars prequel trilogy that seemed like he at the very least WATCHED the previous trilogy before writing the new one. It didn't seem like he even cared about the original trilogy, the Star Wars we fell in love with, when creating the prequels.
I'm grateful to Lucas for giving us the original Star Wars movie. Absolutely grateful. But here's the thing, everything after that came as a result of the fans. And then we have the prequels. At this point, Lucas is nothing but a money grubbing clown who simply just doesn't care about good filmmaking. He threw his fans, the people who made him millions, under the bus. And it isn't right.
