Lucas has changed over the years. I think to argue that he is the same filmmaker he was when he started is false. When he started he was a wunderkind who was able to buck the system and win. But his success was also his downfall as an artist. By earning his freedom from the Hollywood system, he no longer works with people who are willing to question him, and consequently his creative work suffers. Film and television are collaborative efforts. Something Lucas seems to think of as compromise of his imaginative freedoms, when in fact it's the collaboration of the team to bring one vision into reality, that can really boost the strength of a story.
Lucas is running companies now. He has salaries to pay, and employees who are depending on him for a living. I can respect that, and I think it's great that he is as successful as he is. I understand and respect that Star Wars was created as a wholesome adventure series that a family could enjoy. But there is no reason why entertainment can't also teach a lesson, or have some sort of value or lasting humor. One of the very reasons that Star Wars was such a major hit was the fact that it was entertainment with a message. May the Force be with You meant believe in yourself and go for your dreams with everything you've got.
So little of entertainment now has anything equivalent to that. It's just selling something. Add to the fact that George is constantly changing his mind. Endlessly tinkering and making improvements, all the while telling his fans that the films are better. He may have the right to do these things, but don't tell me that you aren't a little insulted when he tells people in interviews that his changes make logical sense, or that they better the story. They don't. When asked by reporters why he is no longer going to make any more Star Wars films, he claimed that everyone hated his new films, so why would he bother making more of them? And yet all he has been doing is rereleasing version after version of them. Creating spin off after spin off television shows. Don't you find that a bit ironic?
Since 2005 when ROTS was released he's said he's going back to make personal art films that no one will want to see. He's done with Star Wars. But that's not true at all. He can't let it go. I would LOVE to see what kind of avant garde films he could make with his resources. But he'll likely never make them.
The anger and frustration with Star Wars is that Lucas is constantly telling people what they want, instead of trusting that his audience can make up their own minds. I don't like it when people I don't know insult my intelligence or talk down to me, and then tell me I'm whining when I don't understand something that makes no logical sense. If a filmmaker or author trusts his audience then they don't have to dumb down their work.
