Teenagers are haunted in their dreams by a scarred figure with knives for fingers. When the kids start to die, Nancy realizes that the figure from her nightmares is somehow causing the deaths, but she can't get anyone to believe her.
Slashers are one of my least favorite sub-genres, but in Nightmare, the horror doesn't come from gore or cheap scares, it comes from the characters being at risk, and adds suspense by blurring reality and dreams. I had to dock a star for the mediocre acting. Johnny Depp's realism in his small role made the rest of the cast look pretty crappy. But otherwise a movie that deserves its place as a horror classic. Great fun.
