This is great news. I was more than certain that the show was getting axed, especially with the American Dad renewal. With a short order (no pun intended) of 13 episodes, I'd expect to see this come back next Spring, once they're run through the gamut of AD/Cleveland episodes early in the fall.
If you got turned off by the admittedly-awful first episode, give it another chance. You won't be sorry.
Man, I remember a time, not so long ago in fact, when I got really excited by new movie news. Most of these just sound boring, probably because they're just rehashes. I'm way more excited by the Hellboy cartoon you mentioned over in the tv news.
