Naqoyqatsi, the third in the Qatsi cycle, isn’t nearly as famous as the preceding two films. (Koyaanisqatsi remains one of my favourite films of all time)
This is partly because the genius cinematographer Ron Fricke, who contributed so much to the earlier films, died before this was shot. The director Godfrey Reggio opted instead to go for a (then) highly experimental digital style of filmmmaking, which left most reviewers puzzled.
IMO it stood the text of time however, and now stands as a prime example of 90s digital art and collage exuberance.
