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.
I a huge fan of This series. I was wondering if Robert Duvall turned down the role in the third movie or was he always written as dead. George Hamilton sucks and he adds to the rest of the cast that sucks for this movie.
