What makes it different from others?

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

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?

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
