Dismissed as puerile and unsophisticated, zombies had a difficult time catching on in American culture. Once they caught on, however, they didn’t let go. (They are zombies, after all.) As Bishop shows, this appeal has many bases. George Romero’s zombies were always social critique. Exploiting their shock value made a point, but other filmmakers soon followed, enamored of the potential violence, gore, and exploitation the zombies offered. Then, following 9/11, zombie movies proliferated, demonstrating that even the undead might perform some kind of catharsis. As Bishop notes, zombies were primarily a movie phenomenon, slow to catch on in literature.
Having read a few zombie novels in the last few months, I have pondered this last point deeply. What is believable, momentarily, on the big screen is rendered laughable with the ponderation of reading. When your brain has time to process what slick visual editing denies, it is clear that decaying corpses would have a pretty tough time getting around—even living bodies have trouble with it from time to time. Zombies, after all, are not really ever literal. They are signs, or even prophets. They point to a reality beyond themselves. Zombies, in reality, represent enslavement—whether literal or figurative—that holds us back from our true potential. No wonder they’ve become such fixtures in a world where opportunity has become effaced and terror can breach even secure borders. They may be lowbrow, but having lived the working class life, I have always had profound respect for the walking dead.
