I think you're looking at the documentary the wrong way. It's not about proving one way or the other, it explores the people behind the movement. Showing their relationships and their interests tells us they are otherwise average people who were unable to find a community of their own until they latched on to conspiracy theories. There are plenty of other resources available if someone is interested in learning the science.

I liken this documentary to another similar one called Jesus Camp. To either side of the issue, it will only reinforce your perceptions of your side. That's only because it's less about the issue itself and more about the culture and people surrounding it than anything else.
