Saw Baraka at the Paramount recently. Amazing movie. Very much in the same vein as Koyaanisqatsi and Powaqqatsi, that is, no plot, dialog, or story: simply a succession of loosely linked images of nature and human activity, with a very good score running throughout. Some amazing locations, including Angkor Wat, the Highway of Death, Everest, the Brazilian rainforest, and so on.
