I didn't see the one on human origins, I'll have to check it out.I saw this recently, during the time honored tradition of crawling through Netflix menus with the girlfriend, looking for something you'll both want to watch and noticing things you think you'll like but you're sure she won't.
I saw both this, and a documentary on human origins archeology. Noted, for later. And then we agreed to watch an episode of the office.
I'm hoping this is even partially as good as ww2 in color, which is awesome but doesn't seem to be on Netflix anymore.
