Eighteenth-century critics believed Gothic fiction would inspire deviant sexuality, instill heretical beliefs, and encourage antisocial violence—this book puts these beliefs to the test. After examining the assumptions behind critics' fears, it considers nineteenth-century concerns about sexual deviance, showing how Frankenstein, Dr. Jekyll and Mr. Hyde, Dorian Gray, and other works helped construct homosexuality as a pathological, dangerous phenomenon. It then turns to television and film, particularly Buffy the Vampire Slayer and David DeCoteau's direct-to-video movies, to trace Gothicized sexuality's lasting impact. Moving to heretical beliefs, Gothic Realities surveys ghost stories from Dickens's A Christmas Carol to Poltergeist, articulating the relationships between fiction and the "real" supernatural. Finally, it considers connections between Gothic horror and real-world violence, especially the tragedies at Columbine and Virginia Tech.
