Reposted from the all things Animated thread:
For a programming block that revolves around cartoons, Adult Swim has always been noticably disinterested in the art of animation. Most of their stuff is very sparsely animated Flash stuff, and some stuff like Tom Goes To The Mayor is more of a slideshow than a cartoon.
Superjail is the antithesis of all that. It's not the funniest show around (in fact, I have a hard time remembering one time I've laughed watching it) but my God is the animation beautiful. It all (appears to be) hand-drawn, and incredibly surreal and imaginative. It's super violent and juvenile, like a Mad Magazine comic come to life, but there hasn't been an episode yet that hasn't wowed me on a visual level. I highly reccomend checking it out.
