The movie's an epic downer, but it's also one of the most succinct and articulate summaries of what's wrong with the modern American industrial food production system, a system that subsidizes cheap, inhumanely produced meat, depends overwhelmingly on corn, is heading toward corporate-controlled agricultural monocultures, and, of course, regularly puts shareholder value ahead of anything resembling the welfare of people, animals, or the ecosystem in general.
Yeah, it's a lot to digest. Food, Inc. doesn't make it fun, per se, but it's elegantly edited and nicely paced, and serves as a great primer on an important issue. And if this stuff is old news to you, it's still worth viewing. The film is a fantastic sweeping overview, and the visuals help make whatever you've read in abstract a lot more real. So grab a bucket of KFC, pull up a chair, and get ready to learn where much of your food comes from. And then prepare to set that KFC down in horror.
