I think it's funny how people still act as if George doesn't care what people think. I would argue he does more than the average person. When you walk around saying you don't care or that you're just doing something for you, it screams overcompensation about how much you truly are looking for validation.
It all over my Facebook/Twitter pages, people screaming in defense of Lucas and almost blaming the fans for him walking away and the whole "How could you!" attitude. The fact of the matter is that ol' Georgie surrounded himself with "yes" men who told him every turd he laid was made of solid gold, so when he found heavy opposition to things he was doing and lower box office receipts he was shocked and is "taking his ball and going home".
I would have been more impressed if he said "You know what, it's time for me to really take a look at where I started with __________ and what made it so great. Time to get in touch with that magic that made people fawn over it. I'm going to step away and then come back for one big hurrah." You could fill in the blank with Star Wars, Indiana Jones... Instead of proving people wrong and showing he still has the juice, he is simply willing to creep slowly into the night. I don't for a minute believe that he will take a good hard look at Kingdom of the Crystal Skull and say "Let's fix it." mainly because he I'm sure can't see the forest for the tree and the people around him still gush about how fantastic it is.
I don't believe for a moment that Lucas has forgotten what made his films so memorable, the original trilogy was steeped in mythologies and references to other masterworks. The prequel trilogy was a "bam bam shoot 'em up" kind of show that even undid many of the mysterious and dogmatic things that he did in the originals.
I like the prequels for what they are and certainly have characters from it that I'm glad we had but it's difficult to say that Lucas wasn't simply pandering to the younger audience instead of making a "fairy tale for adults" that caught on with kids as he has been quoted as attempting back in the 70s. Filmmakers make stories to the masses, they tell their stories on the big screen for others to share and enjoy. If they aren't enjoying it widespread that has to say something. Imagine if an athlete was only performing at about half speed and while they still had their fans and people who would follow them off of a cliff, for the most part they weren't generally liked anymore and that same athlete said "I don't care what people say I think I play great and I'm playing for me." They'd be laughed out of their sport and their arrogance front and center of every ESPN report. This is generally no different.
