Food, Inc.

First off: don't watch this.  It will ruin you.  Second: as an eating human, you have to watch this.  Third: whatever you do, don't watch this while eating.

I think this is well done, I have no reason to question the accuracy of it, besides my being skeptical, but even if it is a little off one way or the other I think it's worth a watch, and personally I think it's worth a second watch.

The preview?  The reviews?  Right here at Netflix.
