Simple and well acted, it has tension enough to knot the stomach.

an ambitious but ultimately ineffective debut endeavor.

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?

This film is so real. It treats its characters with so much care and sensitivity.
