Exploitation of a Psychological Phenomenon and Its Victims
This movie doesn't seem to know what it is. On the one hand, the filmmakers seem sympathetic to the people suffering under this condition, but at the end of the day, it's just an exploitation of their distress.
Whether or not you believe in demons or ghosts or whatever, the people interviewed are actually suffering, and the filmmakers, for most of the film, seem to be on their side. Then we get discussion of how this disorder could spread through suggestion--by exposure to the ideas within the film. So, at the end of the day, all the filmmakers care about is a cheap scare, but if you've ever suffered sleep paralysis of night terrors, a film like this could actually be quite damaging, which seems to go against the film's supposed intentions. In other words, exploitation of victims, and potential creation of new ones.
Is it the goal of the film to make more people suffer? If so, *beep* this film and the people who made it. They clearly don't care about the people being interviewed. Would you take this type of approach when discussing other disorders, like schizophrenia or bi-polar disorder or depression? All the filmmakers have managed to do is take someone's genuinely distressing problems and turn around wearing a mask and shout: "OOGA BOOGA!"
Way to go, A-holes.
