I really dug the new Genndy Tartakovsky show on Cartoon Network, Sym-Bionic Titan. Genndy of course is behind such hits and quality works as PowerPuff Girls, Samurai Jack, and the original (and epicly awesome) Star Wars Clone Wars micro mini-series. The man is an animation master, who happens to work in a crude and deceptively simplistic style. Here, with Sym-Bionic, he cribs from giant robo anime, to much success.
While I was leery about taking our cast of teenage aliens in the undercover high schooler direction, the first episode all works brilliantly, and shows Genndy still has his touch. Any fan of animation, comics, anime, and the like, should give this one a shot!
