Great movie! If you want to be entertained and have a few good laughs, see this movie. The music is also very good,

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

The movie is wonderful and true, an act of love in all its contradictions and complexity

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
