Surprisingly good documentary. You find people to root for pretty quickly. I'd love a prologue.
I debated for a long time whether or not I should take my kids (7 & 8) to see this movie. We have been reading it and they seemed to be handling the content well. After talking with a few people who had already seen it I decided to go ahead with it. My children and I loved it.
The frightening and/or gory parts weren't too bad and the storyline allowed for conversation between the kids and I afterwards.
