I audited his class one day at HB. I thought that the scenes that I saw were amazingly well acted. But I couldn't tell you whether the actors were naturally gifted or whether it was due to his teaching ability.
The feeling that I did get from him was that you needed to be on his wave length (his thinking style) to get what he was putting across.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
