Best two reviews:
1) Entertainment Weekly - Complete Unknown is perhaps most titillating when it quietly observes moments between its central duo, two long-lost lovers hurling nearly two decades’ worth of unresolved pain at each other over the course of a single evening. (Rating: 83) Read Full Review >
2) Screen International - Refreshingly, there is no clichéd love story or illicit thriller that emerges; Marston is pursuing ideas that are far more personal and philosophical, about the masquerade of identity and what it means to that identity when you make a significant change in your life.

Worst two reviews:
11) The Film Stage - Armed with two top-notch leads and a compelling premise, Joshua Marston‘s third feature, Complete Unknown, spends a lot of time hinting at which direction it will go, without going anywhere at all. (Rating: 50) Read Full Review >
12) indieWIRE - The film’s best moments are hollow and derivative, as borrowed from better fictions as any of the names that Alice takes for herself. (Rating: 42) Read Full Review >
