This would be the perfect movie for history-minded 6 to 9-year-olds if it wasn’t aimed at the intellectual level of a toddler. The story of a resourceful, overdressed little girl who wards off the unpleasantness of the Depression one act of kindness at a time, Kit Kittredge stars Abigail Breslin in the title role. An aspiring reporter, Kit chronicles the hardships encountered by the boarders who have come to stay with her family and the “hobos” who beg for work on the outskirts of town. Every scene is numbingly obvious, as if the filmmakers were speaking not to children, but dogs. Why do so many family films think their young audiences are imbecilic?
