It is hard to understand what the hype of this documentary is about. I seen plenty of these kind of documentaries when the basic theme simple dissolve in front of the camera since reality do not follow a script.
But the strange part is the good reviews and even prizes that this documentary got. It has a basic red thread and when that falls flat the documentary kind of tries out ten more possible stories. None of them works.
After reading some reviews it seems that some came to the conclusion that at least some of the people in the documentary has to lie. That is not my take on it. I see it as just a lot of loose threads, and no one can say anyting about them.
But for me the filmmaker seems to want to make a better story out of something that was probably nothing in the end.
I do not know if the documentary director wanted to bring herself into the documentary because she gets angry when things do not go the way she want it, and surprisingly she films her saying that too and question the people in the documentary.
It could be that she knowingly brings in the angle that she is the filmmaker and she do not know what to do when the story falls apart. Then she tries all angles to keep the documentary alive. But I do not think the story is such a meta story even though that would be interesting at least.
