It was necessary a huge amount of recording hours to get this amazing film. You will appreciate that an important part of the landscape and nature of Colombia is not known to tourists. It is a display of grandiosity. It shows a shocking reality and a powerful message. Great quality in filming technique, color, music, and it is not a NatGeo or a Discovery film. The narrator's voice and the story are very well achieved. I think this is the most important documentary of Colombia ever made in Colombia. I really would have liked a longer duration, enough to show many other wonderful sites of Colombia. You have to see it and share.
