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

If you don't like this, we can't be friends.

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

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.
