You can watch Food, Inc. on Netflix for free. I just (finally! sorry Brian/Uncle Bones!) finished watching it on my DVR after recording it on PBS last week. Perhaps it will be on again? Go check, I highly recommend it.
I am really loving the rallying force this movie has been. It is shedding light on what a lot of us intrinsically know. The anger is even good, because you can harness it into personal changes that grow into local changes.
I especially love that Michael Pollan (from Food, Inc.) said on Oprah a few weeks back something to the effect of "we can make a political decision three times a day, for each meal and what we decide to spend our money on".
