Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
