I think we're all making too much about demographics in this stuff. Animation really fills a two-dimensioned spectrum of what it's allowed to get away with an maturity. You have Wall-E, a movie that's pretty tame but kids simply do not 'get' most of it. Just a funny robot. Then you have Cartoon Hangover, where they perform surgeries on a dinosaur with a tree-chopping axe, give the middle finger, and murder a lot. It's mostly immature, but gloriously revels in it. There's a lot of awful cartoons that talk down to children, and the occasional gem where a more traditional 'adult' show goes deep.
And the lines are blurring even more. Ward (the guy behind Cartoon Hangover) set up Adventure Time as a vehicle to explore ambivalence. You have Hussie doing a lot of animation work that... well it's a theme and narrative cluster****, but an ambitious and never-ending one. Venture Brothers is pretty much an ongoing grand experiment in failure. Looking back, even Batman: TAS wasn't 'for kids', it was the vision of Batman fans for Batman that just so happened to air on Saturday mornings.
