Responding to the original question, no, I don't think it's "our fault". It's just George being George.

Is has entirely to do with Lucas own personality flaws, insecurities, whatever you want to call them. He's always been a control freak, but when he was young and struggling (and still at the mercy of others) he wasn't able to have control over as many things as he would have liked. Now that he's rich and powerful, he can be the George he always wanted to be.

It's ridiculous. With what other popular series of films would the fans consider blaming themselves as if THEY had done something wrong? He's treated us terribly in return for all the support we've given him over the last 32 years.

The only wrong thing we've done is pump this guy so full of cash, he can destroy the things that we originally loved. :-(

As far as the prequels go- the man obviously no longer has any taste, so I don't think the prequels could have ever been better as long as he was at the helm.
