The audience for AMC’s The walking Dead is huge. Bigger even than the shambling multitude of corpses that chase its protagonists around our screens every Sunday night. Now that the show has earned its well-deserved eighth season renewal, there’s no reason to think that the end is in anywhere near in sight. The story of the intrepid band of beleaguered survivors battling undead hordes can’t be contained in a paltry eight seasons. In fact, as Show runner Scott Gimple recently hinted, It can’t even be contained by the small screen.
