City of Ember

Parents need to know that this fantasy based on the popular middle-grade novel of the same name doesn't have much to worry about in the way of sexual content, language, drinking, or strong violence. But its constant tension and often-dark mood -- it's about a decaying underground city founded to make sure humanity survived the end of the world -- make it too intense for the youngest viewers. The teenage main characters face challenges ranging from corrupt officials to a ravenous giant mole; they navigate these problems with persistence and resourcefulness.
