Syfy is hungry for a scripted hit. It’s not for a lack of trying. While Defiance, a huge wager on transmedia content, put up decent if unspectacular ratings during its premiere run, the network’s top earners continue to be a mixed bag of WWE (Friday Night Smackdown), reality (FaceOff, Ghost Hunters) and its signature original films (Sharknado). For all that, Syfy’s 2013 prime-time demo deliveries fell 11 percent. With genre shows more popular than ever, there may be no better time for the network to roll the dice on a fleet of high-concept drama series.
