GCI should be used when Puppetry fails. Like intense action scenes or something. Such as having a Yoda throw his light saber into a Clone Trooper's chest and then yank it out. Puppetry can't do that very well with out looking stupid. But any other scene should use puppetry simply because it's hard on actors, and it looks more realistic (since it is real). I mean, even the Star Wars people complained that they had to act against very little.

And it is not getting any better. I heard the girl from King Kong had to really work hard because she was pretty much acting against nothing. It's just not easy on those poor actors. And then you get bad acting, and then the fans get pissed off...

Lucas, you should have learned from the past. The ESB Yoda could kick your ROTS Yoda's ass. Any day.

Puppets look way more real. Look at Jurassic park. The animatronics (sp?) are used for close ups and interaction. GCI was used for distance shots and action sequences. Even 12 years later that movie is bitchin'! Lucas should have taken some advice.
