I loved the ride, but what about Texas 1986? Why do we never get to the people that far back? Clearly there's footage. I feel like I was kicked out of the car close, but too far too walk, to the destination.

From narration, to interviews and various graphics are able to take what is an annoying tune into an interesting search for the origins of the song and, in a greater approach, how songs (or chants) can evolve into a tangled web. Done with good humor and introspection, even if you hate the song (like me) it was an entertaining and interesting journey.

I watched this after it's early release and I don't want to mention a spoiler, but I watched it recently and something significant has been removed at the end. I do like the current ending, describing collective thought as jazz, amazing metaphor, but there was a bit removed after? Why? It really was amazing!
