To quote Zach Handlen of the A.V. Club on the kind of world zombie TV show The Walking Dead has created for itself: "At heart, The Walking Dead is really only interested in one theme: What do you have to become to survive in a world like this one? It's an issue that's come up again and again and again over the years, and the inherent limitation of that theme is the one thing, at least for me, that keeps the show from achieving true greatness"
In Handlen's estimation the show is limited in its range because there is only so much you can do with a plot where everyone is continually forced into the extremes of human behavior. I mostly agree with him and perhaps the answer to this is to set an end date for a serial television show of this kind. There is only so much explicating on the questions "Should I or should I not kill this person, and how!?" a television show can do before it becomes grievously redundant.
