In order to enter the running for "most redundant post" I'm going to be repeating what many others have already said, since everyone else already beat me to it.
For starters, I have zero sympathy for him. Unless there was some kind of underhanded coercion to sell the rights (unless I'm missing some news, there wasn't) then why should anyone feel sorry for him? He willingly sold the rights, and for more money than anyone in this thread will ever see in their lifetime. This isn't some small time independent artist who got screwed over by some corporation while trying to make a living, he has plenty of money and experience in the industry, he should have known better and if he cared that much about maintaining some form of creative control then he should have negotiated that beforehand and signed some kind of legal documents.
Secondly, I don't buy into the idea that we should all be nice to him for "giving us Star Wars". Last time I watched any of the Star Wars films I don't remember there being only a single name in the credits. While he can still be credited for a lot of the work on the original Star Wars films, that goodwill is not indefinite, and he has since done well to systematically discard every bit of it.
Thirdly, while there is a certain amount of poignancy to the whole affair, I think the majority of fans are glad he's not involved. While it might not be so good for George (except for the incomprehensibly large stacks of money, or course) that doesn't mean it isn't good for the fans.
That said, I do sometimes wonder what it must be like for people such as George. How would it feel to have had a hand in creating something as large as Star Wars, only to become despised for your later additions? I sometimes wonder how much the creative works actually mean to various high profile people. How much does all that money and success dull the fact that your legacy is better off without you?
