Really good tense thriller, reminded me of a whole movie devoted to a killer chase scene from an Argento film. It was tense, however, Lucas has to be the worst male protector ever, I swear subtlety and quietness isn't his strong point. Watch this with the lights off and the sound cranked. The atmosphere of dread was well delivered. The ending came either too long or too short of where it should have been, but that's a mild gripe. Overall, a high recommendation.
