Very very predictable, including the post credit scene !!!

just watch it!

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.
