What makes it different from others?

This is a tender, generous movie that likes its characters and presents them as real people, full of flaws and strengths.

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

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?
