The "horror" genre, or "dark fantasy" genre, or whatever you want to call it, is all too often the redheaded stepchild of literature: rarely acknowledged, and never with grace. Well, almost never. Edgar Allen Poe is acknowledged as a classic writer, but he is regarded as "safe" because he's been dead for over a 100 years and just wrote short stories. Occasionally THE LOTTERY by Shirley Jackson or SOMETHING WICKED THIS WAY COMES by Ray Bradbury will be given the recognition they deserve, but for the most part everything in this genre is kept in a literary ghetto, without recognition.
