You can't get a couple of clicks into the cable or satellite networks without seeing a new "zombie" or old zombie series or movie. Humans haven't evolved much beyond the early to mid 20th century where some modern allegedly advanced cultures invented the concept of classifying certain nationalities to be sub-humans in order to justify their extermination or incarceration. The zombie culture is the perfect venue for educating dumb assed kids that sub-humans actually exist and the only way to save civilization is to shoot them in the head.
