I know many people will live and die by the original Scream having the best and most unpredictable Ghostface reveals of all-time, but I'll stand by the opinion that it is outdone, albeit by a hair, in Scream 2, if not for the stellar twist regarding "Debbie Salt," a Gale Weathers superfan who is eventually unmasked as Billy Loomis's mother, Nancy. Add in the bait-and-switch reveal of Mickey, the sociopathic other side of the Randy Meeks coin, who convinces Sidney that her boyfriend is a killer before executing him in cold blood, Scream 2's reveal packs a bigger and more effective punch than simply "movies made them do it."
