And I have a feeling there's more he did in the other episodes.

Why not do some work on the first two movies? Those could use some big improvment. Why not superimpose the original Anakin over Hayden? Why not concentrate on making Episode 3 good right now? It's due out like next May isn't it? The first two made a lot of money, but they weren't heralded as being that good.
There's so much stuff that he did just because he can and not because he should.
