““There are really only two kinds of monsters in the world, which you already know if you've been watching horror movies: Breeders and Non-breeders. So for instance, Frankenstein’s monster would fall into the second category if he was real. He’s a freak, a singular being and once you kill him, he’s gone. Problem solved. The Breeders are an exponentially bigger problem. Within that group you've got slow breeders like vampires (if they were real, which they’re not) which breed in a small-scale controlled way, but mainly to avoid extinction rather than spread. But then you've got the fast breeders, like zombies (if they existed, which they don’t) where breeding is all they do. They are basically walking epidemics, and are the worst of the worst-case scenarios, because such a creature could, hypothetically, wipe out civilization. This is humanity’s greatest fear, which is why at the moment half of the world’s horror novels, movie posters and video games have zombies on the cover. So in any situation like this, step one is to find out what category of creature you’re dealing with. Step two is to anticipate what the creature is going to do next, based on what you determined in step one. Then step three is you find out if the thing can be killed with a chainsaw.””
