Anthony Le’s review published on Letterboxd:
"Koyaanisqatsi" is simply, and bluntly, just a succession of images. Random ? Perhaps to some people. But to most, the moving pictures serve a greater meaning.
This is what film, or "moving pictures" was made for. Exactly this: to document everyday life. I mean, looking at the first films made, they were all documenting just ordinary things you see: a horse running, a train leaving, people leaving a factory. But, with the emergence of George Melies, and "The Great Train Robbery," people found it more entertaining to watch films with a fictional plot. This idea of just documenting ordinary life was rarely, or never tackled again. Well, until "Koyaanisqatsi." But it's relation to classic cinema can't be the sole fact for why it's fascinating. No, the reason why it's amazing is because it can mean anything, to anyone. It allows you to interpret further, over the span of 85 minutes, on what you think these images mean. So if you would rather just sit back, and not pay attention, this film is not for you. It makes you think, and that's the magic of it.
Well, with this, the film would be impossible without great cinematography, as that is what drives the film. Along with this is precision editing, and a very fitting, original soundtrack. Really, the soundtrack plays as a type of "tone poem" for the film, as it truly tells a story throughout the film. So what left is there to say about this film? Really nothing, other than the fact that "Koyaanisqatsi" is like no other film you've ever seen before, and none you will ever see. It's a risky and unorthodox method of filmmaking by Godfrey Reggio, and it's truly a great one.
