The puppets in the OT were a lot more convincing than the cgi in the SE and PT. The CGI in that stuff was especially bad and often seemed to be designed to sort of swagger in your face in a sort of look-at-me-I'm-cgi way, like the unreal way some of the big creatures moved. And there were all these cartoon creatures too. The puppet for Yoda in TPM was crap though. But the CGI for Yoda in AOTC and ROTS was crap too. I have seen cgi that is miles better than the stuff Lucas used in those stupid movies. He's so proud of his fucking cgi and it's total shit. And of course they cgied up Crystal Skull. Indiana Jones and the Kingdom of the Blue Screen.
