Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

This is a must-see and one of the best documentaries - and films - of this year.

One of the best movies of the year! Incredible from the beginning to the end.

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