What makes it different from others?

Good start, but then it gets ruined

Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

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.
