RogerEbert.com has some great answers to questions about his review of Episode III. Head there for the rest, here's one of them:
Q. How you can give the new "Star Wars" movie 3.5 stars when you write, "The dialogue throughout the movie is once again its weakest point: The characters talk in what sounds like Basic English, without color, wit or verbal delight, as if they were channeling Berlitz." Doesn't this make it a movie deserving no more than two stars? Just because a fabulously wealthy producer can afford the best in special effects, does that warrant a rating close to perfection?

A. I got a lot of messages saying there was a disconnect between my star rating and my review. Perhaps there was. Star ratings are the bane of my existence, because I consider them to be relative and yet by their nature, they seem to be absolute.
"Star Wars: Episode III" returned to the space opera roots of the original film and succeeded on that level, and for that I wanted to honor it, while regretting that it did not succeed at the levels of intelligence and wit as it did on the levels of craftsmanship and entertainment.
