I was really surprised that I enjoyed this documentary so much. The information about our nation's abundance of damns, and the negative environmental impact they have had on the landscape and the indigenous wildlife was shocking to hear and see. Perhaps in the world of environmentalists this is common knowledge, but for a person not entrenched in the cause, like me, it was a compelling argument to learn more about the subject and to get more involved. The cinematography is a highlight of the film, and the information is delivered in a manner that kept me interested the whole time. This is definitely a film worth checking out.
