Food Inc. is a crash-course in all of the things that suck about the food industry today and should be required viewing for everyone that eats food. Inspired by the writing of Michael Pollan and Eric Schlossinger, Food Inc. covers the industrialization of animals and crops, the sins of Monsanto (patenting genes), congressional/governmental infiltration by food company people, the profliferation of corn, loss of diversity in food product manufacture, treatment of slaughter house workers, etc. If you've read those authors before, then this is a refresher course, but if you're a freshman-level foodie, there is some eye-opening stuff here.
Although the movie is fairly entertaining as far as documentaries go, it is still very obviously portraying one group as good (organic farmers, the two writers) and another evil (food industry). The two groups as presented are similar to the kind of Good vs. Evil seen in The Lord of the Rings. Based on similar documentaries I have seen on the subject, the film makers could have shown footage much more damning, but I think that they protect their message this way.
When you were little, you were undoubtedly told, "Don't put that in your mouth, you don't know where it has been." This is why everyone should see this movie. You may not feel the need to change your eating habits to avoid industrial food (but you certainly might), a responsible person should know.
Cost/benefit analysis: I saw this in the theater, but my dad paid for my ticket (yay family fun) so I paid nothing. It's not the most ground-breaking message, so wait for Redbox or Netflix to see this one.
