By Wes Craven's third decade reinventing Hollywood horror, the "Nightmare on Elm Street" creator found himself asking, "What's the point of all this slashing?" He embarked on a third act of socially critical and self-reflexive scary movies: "The People Under The Stairs" (1991), "New Nightmare" (1994) and "Scream" (1996). With two of those three titles celebrating anniversaries this autumn, welcome to your "Be Reel" Halloween special.
