I had intended to sift this, but YouTube has made it so that playlists containing more than 50 parts can't be embedded. (well, you can waste your time making the playlists, and they can be embedded, but only the first 50 parts will play). I don't want to sift it incomplete. The entire documentary deserves a place here.

Here is the embed for the first 50 parts:

Here's the  link to the rest of the playlist (all 137 parts):

This is all 26 Episodes. Over 22 hours.
