Let’s hear it for zombies, the monsters for real Americans: “Zombie enthusiasts are a special subset of horror-movie fan. Many say the monster’s low-tech egalitarianism appeals to them. (Unlike vampires, sometimes portrayed as aloof aristocrats, anyone can be a zombie.) Sometimes called blue-collar monsters, zombies who seek the flesh and brains of the living require few special effects, compared with aliens and other monsters. Some say their relative ordinariness makes them scarier.” Also up for discussion: Which kind of zombie is more correct? Your traditional, slow-moving grunter or the 28 Days Later zoomy/chompy type? Think wisely before you answer, there’s a lot riding on this one.
