Lucas is a money whore. He'll slap SW's logo on anything to make a buck. You think he's doing these prequels to "finish the saga"? No. When he did the Original Trilogy, he was risking everything. His career, his money, etc. He had inspiration. And those 3 movies were great. Nowadays, he figures people will shell out money to see a new Star Wars flick just because it's SW. He isn't risking anything, and he isn't inspired. He just wants money.
