I was watching King Corn. Its a really good documentary, its more like a story of how corn gets into our system. They basically go to the middle of the US and grow 1 acre of corn themselves, they talk about how the subsidy affects their farming. They dont blame the corporations as much as they do the government, but the main blame is on the corn itself.
Its free on youtube:
on the related videos there are also alot of free documentaries that look interesting, ill watch those too sometime.
Thoughts?
