This movie is gentle and utterly chaotic, intimate and massive, beautiful and ugly... it tries to be so many things and somehow pulls it off. It tells two stories parallel in time, based on the real-life diaries of two European scientists who traveled through the Amazon in the early and mid-twentieth century. Their stories are some of the only of accounts of Amazonian tribes in written history. The main character and guide in the movie is a shaman who met them both. At times delicate to the point of almost being able to feel the water, at times utterly apocalyptic and grand... to watch this movie is to take a journey through belief systems, through film... and to be brought along by cinematography that is at times unbelievably and absurdly beautiful. Meditative, violent, jarring, peaceful, luminous, ambitious, artful, heavy handed, graceful... it's really an incredible film.
