Whether or not it is better than the orginal 3 is a matter of opinion, of course (I think you'll at least agree that it is WAY better than one or two).
But there is a reason there are more of everything: The Clone Wars (and subsequent battles between the empire and the rebellion) get a lot of this stuff destroyed, which could explain why everything looks so new in 1,2 and 3 and so old in 4,5 and 6.
It's all debateable, of course, but overall I thought it did rather well. My only real complaint is that it does slow down a bit abruptly in parts and Hayden's performance could have been a lot better (Ewan <Obi> and Ian <Palpatine> are of course excellent).
Anyway, I'm hoping that George takes a tip from Peter Jackson and releases an extended version for the real fans with the stuff that was cut out (which is considerable).
@Fred:
Sorry, didn't mean to come of as that demanding, just getting anxious for the next release.
