Ever since he began making his second set of Star Wars movies a decade ago, Lucas said that Episode III: Revenge of the Sith would be the unvarnished story of the young knight Anakin Skywalker's degeneration and conversion into the black-helmeted, black-outfitted Darth Vader, the villain of the first three films. The tale of woe it really tells is that of George Lucas himself, the final chapter in the sad degeneration of a vital, vivid, and highly amusing moviemaker into a dull, solipsistic, and humorless incompetent.
I liked Revenge of the Sith, but it's true that Lucas's dialogue has never been the strongest. It doesn't help that Hayden Christensen is such a poor actor. And his brooding stare is not very convincing in proving he is becoming evil. Oh, well. I wasn't the casting director. In the end, Sith does pull it off, and it is much better than the previous two offerings.
