Well unless you are already familiar with the Satanic Temple that is. I wasn't and I was quite surprised. If Satanists engage in equal rights, clean the streets of trash and do things most would consider Christian ... that is quite a surprise. Even if you are not into "Satan" (and I am not), they even give you a yin/yang balance. As in, if you have this statue put up, we want one of ours there too.
Was quite surprised to learn about a lot of things and this is quite entertaining overall (there's nudity in case that matters to you one way or the other). Now after I watched the movie someone told me that the documentary shines a light on the organisation that does not include some of their darker moments. One is included when we see a member split, but there seem to be more things. For that I guess there is the internet. Or maybe a sequel to this? Who knows
