In my opinion, some of the CGI in Episode 2 looks pretty bad. Overall I think Episode 1 looks a much more polished film. I'm mainly talking about the arena scene in Episode 2, it is a complete joke and makes me cringe everytime I see it. All of the characters look like paper cutouts. However everything else looks pretty cool. I hope Mr.Lucas is willing to hire more CGI staff for Episode 3. That Arena Scene needed A LOT more work.
