What do you think are the best documentaries on netflix and amazon prime video?

Best to write what it is about and why you like it so much?

I can't say the best documentaries exactly, but I've seen a really good documentary series recently called "Explained". Although it is in English, it covers many different topics such as cannabis, cricket, music, … In 20min episodes.

On Netflix and really recommendable.

I'm going to take a look now, thanks.
