Beasts Of No Nation - 2015 - 8/10

Tour de force tale of boy indoctrinated into wartime militia unit.
Though no country is specified, you could toss a dart at a global map and strike conflict.
The Commandant (Idris Elba) leads his charges, convincing them they are impervious.
Rivalries within the unit run undercurrent, as well as rebel politics undermining the Commandant.
I worried this would be a sad or depressing film, but did not find it so.
Provocative, yes. Disturbing, though I accept that humans relish killing each other.
