What makes it different from others?

Lack of good storyline.

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.

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.
