I don't know. I see some great performance with CG as well. As much as the dynamic in ESB with Yoda and Luke worked, at the same time, I can't help but notice how Yoda's mouth is not really enunciating the words coming out of his mouth. Sure he looks like he's "really there" but to me he still just looks like a rubber puppet.

I think it's a testament to Frank Oz that he was able to elevate Yoda's performance to what it ended up being, but at the same time, I definately had to meet him half way on the whole deal.

It just seems like a lot of us aren't willing to do that anymore.
