Well, its not going to fail - it has the name "Star Wars" attached after all. As to whether it will be any good - well, Lucas has got some ground to make up, although the Clone Wars animated series shows what can be done with average material if you just use it right. Initial buzz seems to be fairly promising, but then I also remember when the Phantom Menance trailer was the greatest thing ever... Nah, Peter Jackson is a hobbit. Lucas is more like, uh... any comic character with more neck than face?
