FWIW check out these two documentaries

I first watched them online (various documentary website), and thought enough of them to buy them for my video library.
what I liked about them is the overall balance of both documentaries in terms of showing the balance of needing money and spiritualism in the case of the movie "money and life"
in the second case there is food porn and science in the case of the movie "planeat"
