I saw “2016” on Netflix recently. Wasn’t too bowled over by it. Partly because I already knew most of what he went over, so there weren’t any surprises. Even so, it felt kind of flat and much too low key.
Considering "Ai Weiwei: Never Sorry", "Bully","Detropia" and "Ethel" made the list, I would think the one documentary that probably out grossed the next ten combined would've at least been nominated.
When it comes to documentaries, “flat” and “low key” are more credible, than (say) “strident” and “hysterical”.
