Barely above average...
Other than the ending sequence, music, and the lightsabres (IMO, a bit of a stretch, but adequately animated) this really had nothing to do with Episode III. I wish you wouldn't have included it in your title. The movie itself, however, was pretty much average. It was a little heavy on the unnecessary profanity for my tastes, but that's just my persona preferance. The voices were well done, save a few points where the dialogue and voices differ, especially at the end with the "Where is my hentai" lines.
