I'm pretty shocked there isn't a thread for this already. Shame on you all! It's one of the best cartoons ever created. It has some of the best sci-fi comedy I've ever seen. Easily as good as Red Dwarf or Futurama.
It's aired on adultswim and is made by Dan Harmon (creator of Community). There are 6 episodes out already and it's coming back in March (it's not been broadcasted since the end of January). I'm pretty sure you can watch all the episodes on YouTube. If you like cartoons, sci-fi and comedy you owe it to yourself to check this show out. Trust me, you'll be in love by the end of episode 2.
