I agree that the zombies are the stars of the show. I think however that one of the most interesting aspects of these types of stories is the reaction of human beings. Whatever caused the zombie otbreak in WA has caused two primary reactions in un-infected people in my opinion 1. Agression and a desire for power over others(The Mallers). and 2. A desire for a group to belong to for both survival and companionship(The Tower Crew). I am generalizing I know but I think these feelings drive the motives and actions of both groups leading them to engage in both extermly selfless and extremley selfish actions. It is these decsions that make them so compelling. Plus, as the zombie threat increses perhapes the Mallers and the Tower Crew may have to embrace the whole " the enemy of enemy is my friend" idea.
