The fact is, few shows ever return from the dead. For every FAMILY GUY that pulls the Resurrection Trick, there are a hundred others like THE ADVENTURES OF BRISCO COUNTY JR., PUSHING DAISIES and 1991’s DARK SHADOWS that never emerge from their metaphorical crypts. Even the patron saint of untimely television deaths, FIREFLY, only managed a post mortem spasm in the form of the SERENITY feature film. TV shows are hard to make, and even harder to revive once a network loses faith in them. It’s not a coincidence that the few programs that manage the Resurrection Trick usually do so in another forum. VERONICA MARS, cancelled by UPN, is returning in the form of a crowd-funded feature film, while ARRESTED DEVELOPMENT, killed by Fox in 2006, returned this year as a Netflix series.
