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

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

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