It's not great by any means, but it's a pretty good movie that didn't leave me filled with regret for investing time in it.

It is interesting even when nothing much happens, which is for most of its 3-hour running time. Read full review

Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.

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.
