3. Carnivàle
Set during the Great Depression, Carnivàle tells the complicated story of a farm boy from Oklahoma and a minister that are caught up in a war between Heaven and Hell. Does this sound interesting? It does to us, and that makes it even more annoying that the show only lasted for a couple of seasons. So much wasted potential!
There were supposed to be six seasons of Carnivàle, but it was all cut short after only two, the show airing from 2003 to 2005.
