Oh, I'm not complaining, trust me. Overall I think they looked astonishing. There's a few things, specifically in AOTC that seem unfinished. The part where Mace, Obi-Wan and Yoda are walking through the Jedi Temple. It's not very well textured nor does Dexter look great either. (The Jedi temple was vastly improved in ROTS.)
But in general they do look fine. I don't agree with the common criticism (there was too much CGI) because it was essential to the vision George had and the kind of movies he wanted to sculpt. Could they have used less? Sure. Am I fine with how they did it? Yes. Just that a couple of things here and there didn't hold up as well as everything else.
