The documentary is well made. Lots of original material, interviews with ex members. No annoying voice-over or anything like that. Its really masterfully edited in order to be able to tell the story in such an authentic way. Also nice it caputures the time period contect of the story. Its a period of over 20 years so its interesting to see other things going on that might have inspired or influenced the cult. What I find lacking is that it tries to hard to explain what happens to much from the perspective from the cult members. They do have some outside experts on cults and psychology and all that but what happened is only discussed very broadly, about general techniques used by cults to "brainwash" people. What is unique about this cult is that it started quite large but over the course of those 20 years more and more left, only leaving the people that, well to be frank, apparantly were not 100% there.
What I kept thinking when watching all the cult members performing some acts: These people are obviously completely insane. Not only because of the eventual suicide but also with other things, like performing dangerous surgery in the form of castration on their own members. And of course literally looking at Star Trek for inspiration. I thought the moment that they returned a fancy telescope to the store because they thought it was broken, they couldnt see the UFO through it. Very telling... I had the idea if I was watching a documentary of the local psych ward instead of a cult at times. Usually there is at least some form of coercion by the cult leadership through hierarchy or some other method. People are prevented to leave by threats or something. Nothing like that here, they even all went to Seaworld just before it ended.
Especially because the group was never violent in any way, or tried to hide what they thought, you really got to wonder why these people were never helped. Everybody seems to have been thinking: Oh well, if thats what they want? Or that is was sort of funny to watch these idiots make a spectacle out of themselves. Anyway, the second half of the final episode is quite interesting as it shows all the reactions the event got. But for the most part during the 4 hours I was thinking: Im not watching a documentary about a cult, Im watching home videos of people suffering from mental illness in desperate need of help.
