I'm not sure why everyone is talking about CGI. The Prequels were weaker films because of poor plot, dialogue, and directing. CGI was still kind of new then so some shots looked way too cartoony, but by the time ROTS rolled around I thought the CGI looked great in that.
It's 2014, I'm sure that any CGI used will look great. I'm more worried about the storyline at this point.
