"Compliance" is a shockingly terrifying film. As I watched the events unfold on the screen, knowing that they were tightly based off a true story, I had difficulty maintaining my breathing. With a sinister visual style from the start, filled with tight macro shots and a simply greasy aura, as well as powerful performances from all of the cast members, most exceptionally Ann Dowd, "Compliance" transcends from its fast-food setting into something much darker, and much more haunting. The abuse of the young cashier is repulsive. "How could you do that?!" you will continually wonder, wishing the words would escape your head in the form of a scream. This film is frustrating, vexing, and equally engrossing, almost as if the story itself doesn't satisfy man's need for vicarious horror. "Compliance" forces me to question my fate in humanity and the limits of the 7 billion people with whom I share this Earth. Ultimately this film is a sickening narrative, a narrative I might as well wish I had never seen. Must you watch this? No. Is this a vital piece of cinema? No. Is "Compliance" paralyzing, appalling, thought provoking, and, most brutally, true? More than you could ever imagine.
