I dont care about it at all if they use puppets or CGI.
first of all, saying star wars needs puppets is completely wrong. star wars is not about puppets, its about working at the hight of technology, because thats what they did back in 77. they didnt say "whoa, lets use puppets and models", they said "lets work at the frontier of sfx" and thats what they did.
second: the cgi was hardly a major problem of the prequels. they could have been perfect films even with the cgi.
and third: yoda was a puppet in episode 1, and it sucked, they replaced it with cgi for the blu ray and honestly that was much better. surely there are a lot of crappy cgi in the prequels but I would never go so far and say they need to use puppets and models under any circumstance.
