This is a TV nature documentary. This starts with a lot of slow moving river beauty shots. Willem Dafoe's narration is a constant throughout. Then it's a lot of archival footage of mankind taming the rivers. After that initial section, the movie becomes a rotating snippet of various modern day scenes of rivers around the world. It may be only seventy five minutes but it feels longer. Mostly, I'm not sure about the point of it all. It certainly looks pretty. There is no denying the beauty of the cinematography. Dafoe's narration keeps going and going. One can view it as poetic but it left me grasping for meaning.
