Intense, gripping, stylish and poignant

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

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.
