Absolutely absorbing and on par with the best David Attenborough documentaries. Willem Dafoe does a superb job at pacing the narration to the incredible imagery and proves that well written and narrated documentaries do not need the distraction of talking heads.

I can't believe how slow, dull and pretentious this film is. There is no imagination and the narration (script) made me cringe.

How could such a potentially exciting subject be rendered so flat? I don't know what the aim of the picture was, but entertainment, excitement, joy, they were not on the list.

For me there would be much better uses of my time.

I saw this incredibly interesting Doco last month at Sydney's Verona Cinema. It relates disturbingly how Man has Damned, Bridged or altered the course of every River on this very sad, at this moment, Globe. It should be shown at EVERY School, college, Government and Corporate meeting room around the World before it's too late to do something constructive to fix at least some of the Rivers destruction.
