Streaming Now...Documentaries

In the winter, I tend to hibernate more, and lately, I seem to be streaming documentaries, in between the nightly rotation of news and political commentary, of which my husband never tires. 

There are a lot of noteworthy documentaries available on the various streaming channels, and here are three that we have watched recently. 

The White Helmets. 
This 40-minute documentary about a group of first responders in bomb-ravaged Syria is streaming now on Netflix. 

13th
Also streaming on Netflix, this documentary, named after the 13th U.S.Constitutional Amendment, is about the American criminal justice system, tracing from post Civil War to current times. 

Where to Invade Next
Streaming on Amazon (and Hulu, I think), this was Michael Moore's look at European public policy that he would like to bring to the United States. 

What are you streaming these days? Any recommendations?
