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.

Amazing worth wacthing. So good. Biased but well made with many good points.

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
