I mostly want to point out that despite some reviews claiming otherwise, some of the people in this documentary are not actors. The older woman who leads a witchcraft session with naked young ladies and the young woman getting married were both famous "real" witches back in the day. The husband as well. I've forgotten their names but if you watch the movie just go check online, there's lots of info about them. I had to research this since I was basically 50/50 for either believing it or not and a bit sad to see in the other reviews that it was all faked with actors. So good people, this stuff is real, basically the only things not completely provable are the Finnish ceremony and the black mass, but I'm personally quite sure that they were not made up. Why would they be? It was very easy to find stuff like this happening all over the world.
I guess people were more open with their occult ceremonies at the time, but they're still happening, take for instance Marina Abramovitch and all the famous people and politicians who go to her ritual parties. Rappers and musicians are openly worshiping Lucifer etc.
So sure, this looks a bit silly but the witchcraft was real.
