The voice for Ashoka isn't badly done, but the eyes really get in the way of that. The voice for Padme doesn't sound right at all. Luminara comes off like a poser, like so many of the prequel era Jedi.
Interesting to know that Ron Perlman voiced the guy who kidnapped R2. I thought there was something familiar about the voice. Really enjoyed Hellboy 2 recently -it was much better than the first one. The animation for his character on the Clone Wars show is one of the better done character animations.
Overall the show has a very shallow feel, if maybe more alive than the movie.
