Well, anyway, as lukewarm as I was about the puppet they used in TPM, I think TPM was the only prequel that had the right idea about how to use Yoda. They actually used the puppet in conjunction with a couple of shots of CG where it was needed. It was used in a wide shot of Yoda pacing, so it actually looked like he was there walking. Then when it closed in, it was the puppet again. That's how I thought it should have been done. Rather than the complete CG Yoda used in the other prequels, they should have used a puppet except where necessary.
