This serves as a tamer, but every-bit-as-powerful, version of Schindler's List (at least in-so-far as it portrays the reality of the Nazi concentration camps and the hopelessness and unfairness suffered by its prisoners). Perhaps because this is a "fable" rather than biography, it manages to portray the awfulness of war in a more subtle way - without all the gore and through the eyes of a child. It's still quite intense, though, and would only be suitable for teens and adults.
