Heartbreaking I am an American of Palestinian descent, and this film broke my heart. Unfortunately, the filmmaker only got to tell one side of the story before he died. The way some of the Palestinian adults (note not ALL of them -- for example, one boy's mother is shown begging him to stop his martyr talk) radicalize their children is shocking and upsetting. However, had Miller lived, he probably would have show some Israeli adults doing the same.
No matter which side you're on, this is a very sad and thought-provoking documentary. Anyone who's interested in the conflict in the Middle East should definitely watch it and see the level of desperation that the people there have reached.
