Terror (2007) dir. Ben Rivers

This masterfully edited compilation documentary analyzes the morphology of the horror film. Stringing together the most common tropes and scenes of slashers, zombie flicks, slumber party massacres, etc. into a single metahorror opus, Rivers not so much deconstructs the genre as provides a tribute that reveals its limitations but also its visceral power. Its films like this that explain why I do film programs like Experiments in Terror Noel Lawrence, Provocateur Pictures.
