For the past couple years I’ve wondered why so many people I know are fascinated with zombies. At first I thought it was just the next “vampire thing”—you know, being morbidly intrigued by super-powered monsters—but that didn’t fly because zombies are just plain gross. Vampires may be deadly, but they’re always sexy, some are friendly, and they’re a minority. Then I thought the interest stemmed from the exhilarating horror of it, the car wreck you can’t look away from. I’ve definitely known people that just love to see disintegrating or rotting flesh, guts oozing out of open wounds, or gallons of blood squirting at the camera. But that attraction of gore couldn’t explain why almost everyone I know is into zombies in one way or another.
