“The Black Cat” or “The Tell-Tale Heart

Poe has often been called a master of the macabre. Much has been made of the use of narrators in his stories (e.g., “The Black Cat” or “The Tell-Tale Heart”) Analyze his use of narration in “The Facts in the Case of M. Valdemar.”
Horror is a much-maligned genre; some have even claimed that it’s inherently sadistic, immoral, and/or pornographic. In his work “why we crave scary movies,” King writes: “The mythic horror movie, like the sick joke, has a dirty job to do. It deliberately appeals to all that is worst in us.”
Defend OR refute King’s statement using either Carrie or Poe’s “The Facts in the Case of M. Valdemar.” Be sure to provide evidence from the text.
