I agree that he is a perfectionist: about the wrong stuff. He put incredible painstaking detail into his digital Yoda and his other computerized creations, forgetting the story in the process. In my opinion, he should have gone with a puppet for Yoda in AOTC (wouldn't that really tie the trilogies together?) and worked on the dialogue, casting, and acting more. Then we wouldn't have the ridiculous Yoda/Dooku saber scene.

I am a believer in the theory that the less resources a good director has, the better his movie is (up to a point). Because instead of relying on fancy special effects, huge sets, and everything else to drive the story, he has to find creative ways to make the dialogue and action good enough to carry the movie. You get interesting camera angles, humourous moments, and other things that they wouldn’t have bothered with (with more money) but that they need to keep the film interesting. This intensity and high acting standards are often lost when the director has other things to fall back on, and I think that’s what happened with the Prequel movies.
