I've got nothing better for Trick Or Treat today, so I'm going with a pretty simple one:
Which is scarier: Vampires or Zombies?
Keep in mind that i'm talking Stokerish vampires and Romeroish zombies.
I find zombies more disgusting, but vampires are much more disturbing. The best vampires are scary because they corrupt their victims rather than just infect them. Zombies are contagious, Vampires are seductive...
