Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

It is an exhilarating, distressing, funny and profound film, with one of the more memorable film scores in years,

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

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?
