I think it's because, in the 3 1/2" scale, animation such as this works better because there is less detail than trying to capture actual human forms or the CGI ideals that LFL is trying to pass off as "realistic". When there is less detail in the media format, it translates much easier to the sculpted form.
Or maybe it's just because the Clone Wars Animated Series rocks ass!
Six of one...
I just wish the animated figures had better articulation. More possible poses would be welcomed.
