It comes from established Walking Dead pedigree
By launching a spinoff series, the network is taking a risky route with a property that has become a monster hit. As fans well know, the television series is based on Robert Kirkman’s long-running comic book, which has spent several years establishing plot lines and working out the character and story beats before the TV writers adapt those concepts. A spinoff provides freedom, sure, but there’s also no roadmap. Luckily, Kirkman himself is working on the pilot script, along with Sons of Anarchy producer Dave Erickson. Kirkman’s hand at the wheel makes us feel a lot better about this gamble, along with fellow Dead producers Gale Anne Hurd and David Alpert.
