Human Flow (2017)

Ai Wei Wei made this film, which was short listed for Best Documentary this past year, but did not quite make it onto the nominated films.  A shame, although his name recognition internationally is so high that I suspect this will get the attention it deserves. 
More than 65 million people around the world have been forced from their homes to escape famine, climate change and war, the greatest displacement since World War II.  The filmmaker examines the staggering scale of the refugee crisis and its profoundly personal human impact, and does so in a way that the magnitude of the problem starts to become understandable.  The fact is that even when it is done as well as can be expected, it is horrible, and the truth is that almost none of it is being done at all well.  The flow of people seems overwhelming and inevitable, and as he points out at several points in the film, the average refugee will spend 26 years being displaced before being able to return home, and in some cases it is far more.  This is streaming on Amazon Prime, so accessible.
