Koyaanisqatsi

So, this is the fifth time I've watched Koyaanisqatsi (I watched it four times in a row my sophomore year in high school, as I had to sculpt a minute-by-minute analysis), and honestly, it didn't get much better.
The music sucked. There is a joke about the composer:
Knock knock!
Who's there?
Phillip Glass!
Knock knock!
Who's there?
Phillip Glass!
etc. etc, which is a pretty good representation of his music. It's supposed to be mesmerizing; I only got extremely bored and annoyed.
The scenery was adequate; there were several powerful shots, such as the garbage, and the beach next to the factory (apparently, if I remember correctly from 10th grade, the buildings represented round tombs/gravestones, symbolizing the death of nature.) I suppose the atomic bomb would be compelling too, if I didn't know from research that the shot was Photoshopped.
I think that the movie could have made the contrast clearer. I could tell that the cinematographer was trying to contrast nature with urbanity, yet it had quite beautiful, peaceful shots of the city, which confused me.
The meatpacking part was my personal favorite. The hurried frenzy of the sausages and hot dogs interposed with the busy freeways was quite comical, and was kind of disturbing, comparing cars to hunks of meat (but a good kind of disturbing).
I also liked the Hopi cultural aspect of the film. It brought a sort of ancient, mystical feel into the movie, which did contrast nicely with the urbanization of our society.
However, other than that, I found the movie dry, and not at powerful as advertised. And long. The shots were too long, and slow. I felt that if I watched the movie at 2x, I would be a lot more supportive of the movie. However, spending 10 minutes on the same shot, with the same arpeggio playing over and over again gets extremely irritating.
So, overall, there are several good parts of Koyaanisqatsi, but it is overal slow, dry, and boring.
