Query: A revolutionary film

You'll never look at a hamburger (or any other meat or chicken or food product) the same way again!I have long been a fan of a no-red-meat, organic food, and locally grown products, but now I am a Believer, with a capital B big time.Furthermore, there is a scene in this film that epitomizes the nature of command and control in organizations, which is instructive to anyone who is a student of systems and how they ultimately and predictably break down. The same beef processor depicted at this moment in the film had to recall thousands of tons of beef product a week or so after I watched to movie due to exactly the sort of e-coli problems the film was showing viewers they were bound to have.Finally, there is a farmer from Virginia in this film who ought to be made head of US Department of Agriculture. There are a number of real heroes in this movie and the movie itself constitutes an act of courage in the face of monopoly capital.
