"...And they charged the people a dollar and a half to see them." No, no, no - this is not worthy the subject. It's really not Joni Mitchell's style to throw together a bunch of images and moving pictures and think it will make an interesting documentary. For example, take this part about sus chords - suspended chords. I suspect that not everyone watching was sure what exactly it was about. Like how they help to add color and movement to chord progressions. Instead, we get a lot of available jaded replays that we could put together ourselves. If that would make sense. "They paved paradise and put up a parking lot".
