While I don't know if I'm going to bother with it or not yet, I really hungered for some 1970's style R rated animated comedy films. Seems that was a completely untapped market. I wouldn't doubt that most of the cast is from SNL since most animated films seem to feature a lot of them now. But at least they have distinct enough voices. Like I said a while ago somewhere else, Dreamwork's folly (before they went full CGI) was casting good looking actors and actresses with no distinct voices whatsoever that didn't give the characters any personality. Like that forgotten Sinbad movie. Quite a lot of voice actors start their careers as comedians, like Tom Kenny. Phil LaMarr started out in MadTV, and he's also a staple. I don't see why you wouldn't want a cast that has experience with impersonations and creating weird characters.
I do like how a good deal of the SNL cast also does television animation as well. There's that series Nature Cat that utilizes mostly SNL talent, except for Kate Micucci and the odd Sesame Street puppeteer. Mainly because it's recorded in New York.
That said, what I find a distinct lacking of is an adult animated action series. Even televised the best we can get is still action comedy. If there's anything I can safely say Japan has kicked the US's butt in in terms of animation, it's the lack of animated action films for the older viewer. I'd love to see something like Golgo 13 or Goku Midnight Eye come out of the west. I at least give credit to DC's line of DTV's. The adaption of "The Killing Joke" is getting a hard R for its disturbing and dark subject matter. Everything else at least manages to be PG-13, so there's that much.
