Adventure Time started out with a pilot on Nickelodeon. Oddly enough, the network didn't pick it up, but Cartoon Network saved it and put it on the air. The first season might have been a little convoluted and somewhat lacking, but it was still watchable. Season 2 started a trend where the show got better as it went on, not just in writing, but in character development as well. The show is funny, quirky, cute, terrifying, and overall, awesome.
My rating: 8/10
