At this past weekend's WonderCon la-di-da, Warner Bros. Animation and Cartoon Network unveiled a deeper look into their updated ThunderCats series, which has an distinct Avatar: The Last Airbendery vibe. And that is not a bad thing in the least.
Given that Avatar is the best—and perhaps only—recent example of long-form storytelling for a young audience, I'd would be thrilled to pieces if these new adventures of Lion-O and his aides de camp managed to approach the depth of emotion and awesomeness of action that Nickelodeon's long-running series had.
That said, the animation seems to be taking a few too many anime shortcuts—mouth open! mouth closed!—it lacks Avatar's fluidity. Still, I did get a little chill when the boy king gave us the ol' "Thunder ... Thunder ... ThunderCats, ho!"
