A great mystery weaves through the darkness with a certain momentum. It dodges left, cuts right, moves in all directions and then suddenly circles around and flips on the lights to reveal an intricately designed puzzle that’s not missing a single piece. As the credits role, it makes you believe there’s no other way the film could have accounted for the exact sequence of events, and it makes you want to rewatch to see how well everything holds up with your newfound knowledge.
