Carnivàle was one of many high-concept HBO shows from the early 2000s. It attempted to tell the story of a looming confrontation between good and evil set within a traveling carnival that housed more mysteries than carnies, runaways or fugitives. After two critically acclaimed seasons and one breathtaking cliffhanger, HBO's Carnivàle was canceled in 2005. In the years since, however, the TV landscape has changed vastly, to the point that a slow-burn story like Carnivàle is no longer as uncommon as it has been in the past.
