It's fun, it's light, [but] it has a hard time when its tries to get heavy.

It's complicated... I really like the directing, acting and writing but, there are issues with the way it's shot that I just can't deny. As much as I love the storytelling and the fantastic performance but, there are also certain scenes that didn't need to exist.

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

The film never slows down or bores, plunging from one harrowing sequence to the next.
