I agree Lucas has been caught with his foot in his mouth a few times. But, originally, the story of the original trilogy was going to be told in one movie. Not the "Lost Cut", which DOES NOT exist! After writing the story, it was just way to big to do as one movie. So it was divided up into 3 parts. The first part (episode IV) was then fleshed out and re-scripted several times into a screenplay. The rest was put on the shelf, and if Star Wars was a hit, then he would continue the rest of the story. Thats how it became a trilogy. I believe the Special Editions were a test to see if the CGI worked and if the public still had interest in Star Wars, so he could go ahead and make the prequels. Lucas will never be able to top Star Wars, so he keeps fucking them up over and over so he can keep releasing them.
