It's ironic. I find myself nodding my head at Ian McDiarmid's insertion into empire, but grimacing at Haden Christianson's insertion into Jedi, even though logically, it makes sense.
The Gungans and naboo are passable I suppose, though the insertion of the Jedi temple into coruscant doesn't make a lot of sense (surely the emperor would have destroyed it?). The altering of the script on the tractor beam shouldn't have been neccesary in the first place, so that's a good thing.
Only thing I'm not sure about is Jabba. He's never looked real in that scene, and the scenes on the site seem to indicate he now looks different, but not neccesarily better. It's the sort of thing you have to see in motion.
