I think you guys are misunderstanding what I mean by "real." I'm not talking real as in looking like something real. I mean real, as in they were real and more concrete. For instance, look at Dexter. The effects were great there, but you could tell it was CGI and Obi-Wan was reacting to something that really wasn't there. In the OT, Yoda is really there, whether he's a puppet or not.
