I'm being generous with a 6, maybe its closer to 5. I was looking forward to watching based on the high rating it has on imdb as I love documentaries. Unfortunately I found the documentary to be poorly put together. Don't get me wrong, I feel horrible for what these kids had to go through and there was definitely something sinister going on here. I just didn't enjoy the narrator, the lack of cohesive interviews. It would have been much better with some parent interviews, maybe someone from the actual school. There is no doubt some of these kids were troubled, one spoke of using heroin during high school. Unfortunately it all came out flat for me.
