Zombies are one of the most resonant of pop culture monsters, in large part because they allow for so much thematic possibility. In one sense, zombies represent inevitability, the slow, inexorable decline of each individual due to mortality and of society due to the flaws at the core of those who make it up. Zombies in the traditional sense are sluggish and unhurried because the speed with which they kill you is virtually irrelevant. Your death is inevitable. It will come eventually. You can run, you can hide, you can fight it as long as possible, fight until your last breath, but you will die. You can beat back the hordes, beat back every last undead monster that comes your way, but still, they will win, because eventually, you will lose.
