Adult Swim hasn't been good, save for the odd series here and there, for years now. AHTF was only good in the first two seasons, then it started getting more and more creepy, just for the sake of being creepy. SeaLab was awesome, but alas is gone. Space Ghost C2C was awesome, Harvey Birdman was great, also gone. Venture Bros, and Robot Chicken (sometimes) are all they have thats funny anymore, outside of Family Guy and that's not even really theirs.
I can't stand most of their original stuff. Squidbillies is just the most retarded peice of crap that's ever been put on television. 40 Oz Rat wasn't much better. Frisky Dingo trys too hard to be funny to actually be funny.
Anime wise, the only show I like that they're currently showing is Samurai Champloo, and I haven't watched more than 2 episodes on Adult Swim because I can't stand dubbed anime.
