Just wanted to pass along a recommendation for the movie, Children of Heaven. Created by Iranian filmmakers and set in an Iranian city, the film shows the life of a family that is as dependent on one another as it is joyous. It shows the hardship and blessedness of poverty. It's bright colors against gray and brown backgrounds, and its sound, which was done almost completely without music, are as much a part of the art as the story itself.
Seeing kids so full of love for one another as the siblings in this film, changes my expectation for what is possible for the relationships between my own children. As soon as they are able to read subtitles, I will show them the movie, too.
