A remarkable achievement in documentary film making. I view this film through the lens of my professional training and occupation as a measurement specialist. Imagine an extraordinarily difficult test on which you must get a perfect 100. No 95, not 98, not 99. It’s either 100, that is perfection, or death. A 99 is no better than a 58, say.
If you have the stomach, by all means see this sure bet to sweep its category at the Oscars, Cannes, etc.
