I really don't get the hype.

Don't Believe the Hype

The film never slows down or bores, plunging from one harrowing sequence to the next.

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.
