I'm withholding judgement for now. I think with the right talent, they can do a good job. I think that Episode One overstayed its welcome a bit on the Podracing, but I really didn't mind and even liked Episode Two and Three.
Podracing was a great game. The movie sucked terribly. I can't begin to imagine how Liam Neeson could speak that cheesy dialog, and I've never been fond of Ewan Mcgregor. Natalie Portman was ok.
High Science Fiction aside the characters stories were totally unbelievable - the main blot boring.
The graphics were ok, but not anywhere near appealing enough to do anything to save the movie.
I was so tainted by Episode 1, i couldn't watch 2 or 3 with an open mind. But I might have to do that again.
I really loved the first three movies. I remember going to the first movie. It wasn't my pick, but I didn't yet drive so was at the mercy of my older sister who did drive. She wanted to see it badly. I got hooked.
I doubt if Disney will do any worse than Lucas.
