This documentary (the first in a trilogy series) chronicles the lives of the West Memphis Three, three teenage boys from Arkansas who were arrested and convicted of murdering three young boys in the woods. The evidence was thin, with the teens largely convicted based on their appearance and hearsay, most of which was later recanted, as well as flimsy testimony from "experts," which was later proven to be largely false. 'Paradise Lost' is more than just a heartbreaking documentary about three young men who were sentenced to spend their lives in prison for a crime they likely didn't commit -- it's also an indictment of a broken justice system. That may not seem like enough to make you think the film belongs on this list, but the maddening story and the frustrating trial are all made so much worse by incorporating blunt footage of the three dead little boys as they were found in the woods.
