Then, there's no other side to Yoda in the Prequels if we've already seen what he can do in his semi-younger days. Lucas had to do somethign to give Yoda a bit more to do. I'm glad he went toe to toe with Sidious. And it cements the reasons why he is the way he is in the Original Trilogy.

And Mike O, I think Weta does deserves alot of credit on Gollum. But, that doesn't change the fact that at times, they didn't get him totally right with interaction in his environment.

That's one of the main reasons why Dennis Murren made it a point of emphasis during his work on Hulk to make sure that Hulk blends in and interacts with his environment and he pulled it off wonderfully with that film.
