We didn't do this in a while, so lets suggest some documentaries in the comments below. I'll leave the thread stickied till daytime Friday 1st of September. Top voted will be the Featured Documentary for the weekend. Make it a good one, and give a free streaming link.
Previous featured documentaries are listed in the wiki.
Get your suggestions in quick so they can accumulate votes. Multiple suggestions welcome. Thanks.
