The story-line and the drab classroom setting connect so effectively with the blind, rigid fundamentalism and totalitarianism that so much of our world is plagued with. It brings into sharp relief the dilemmas faced by those in similar positions, and it made me question just how would I react in a similar situation.
Simple as is the setting, the story line, the techniques etc., the impact and effect far outweigh the perceived simplicity. Haunting, and morally jolting are, I think, apt terms to use in respect of this movie.
I would highly recommend this movie, and especially to parents and to teachers of ethics and religion.
