The Usual Suspects (1995)

A complex web of intrigue and allegiances is weaved through basically a two-hour long monologue and shown in flashbacks, the ultimate outcome of which is the largest deceit of all. What really works here is how the concurrent story-lines are played - first the actual drug bust, then the interplay between the characters, then the looming question of an unseen character's identity. Each is played out and each carries as much weight as eachother, allowing the film to not only suck you in, but keep you there and on edge for the duration, when everything is wrapped up so neatly.
