I know this is off-topic, but do you know why “Night of the Living Dead,” “Day of the Dead,” etc. were horrible movies, aside from their lack of redeeming characters? Zombies are the least threatening monsters every imagined. All you have to do is walk (not even run!) away. At least ghosts are mysterious. With zombies, what you see is what you get: they move slowly and they like to eat intestines, and not much else.
eat brains.
You've never seen the movie "28 Days Later" have you? :-)
