The true aspects of Appalachian and deep south horror is rural decay, stagnant water, environmental destruction, early death, child workers, and the abuse of the working class. In other words capitalism.
@Saint_Dionysus I've had the chance to talk to someone from there before. Redneck "both parties are evil" type. He said not just the same thing, but that it's -been- the same thing since before the civil war.
@Saint_Dionysus On that note, "Tucker and Dale vs. Evil" is a masterwork of cinema.
