This was disturbing to me because I know what it is like to be the one people bully. It was hard to hear how they were mentally torturing her. This piece also goes to the heart of some mental issues, as the victim is being convinced there is something there. She knows its not true, but believes it is, and by giving into that belief, it leads to madness. That this idea can be communicable is really disturbing, so that the fear and horror is coming from just a simple idea, like a mental virus. I think we all have those ideas of something being true when it is not, that feeling that there is something there when you know it can't be true. That you absolutely cannot step on that crack in the sidewalk, even though you know nothing will happen. And the way the idea is forced upon her, using her need to be a successful actress and exploiting her is so horrific. All the people participating in her destruction, even though they are unknowing. The hero is the one girl who leaves and even attempts to save the lead. She doesn't know the details, but she knows this is going in a bad direction and can't go any further.
The only part that is out of place is the narrative piece of the fan club. Their own social paradigm is a distraction from the group dynamic of the film makers, and it doesn't really contrast well, seeming somewhat pointless until the end. They use the one guy as the example of how the madness can be spread and the horror of having to find his 'girl friend' to convince him is sad, but it seems to hammer the point of the suggestiveness of the film in a somewhat over bearing way. I think the dynamic between the two groups of people needed to have more synthesis to really give an emotional bang to the final horror. But, the story of the film makers is very disturbing and works well, and the idea carried over to the film watchers really carries weight.
