So have we reached a consensus that horror sucks as a category?

A couple of the scariest stories that I have ever read are A Good Man is Hard to Find by Flannery O'Connor (short story) and In Cold Blood by Truman Capote. Only realistic scenarios involving non-imaginary things and people scare me as an adult. Though the film that left me with nightmares for weeks after seeing it as a child was The Creature from the Black Lagoon.
