Well, I only needed to read part of the review to conclude that Ebert is an elitist moron. Just because the animators chose to employ a stylized character design rather than going for photorealism, he assumes that's because "corners were cut" on the animation. That's stupid -- like assuming that Picasso was too lazy to make his paintings look like real people. The goal of the creators of SW:TCW is to embrace stylization of the sort seen in the previous, 2D-animated Star Wars: Clone Wars miniseries. According to an article I read at Newsarama yesterday, they were inspired by the look of the toys based on the SW:CW characters, which showed them that the look of those characters translated to 3D in an interesting way.
Now, I'm not saying I particularly like the design style they've used or that I think it works well. But if Ebert can't understand the difference between deliberate stylization and laziness, then his opinion is not worth listening to.
