Homey and nostalgic, this musical means to emphasize the importance of laughter in the face of tragedy. But the sob stories overwhelm the charm. A dying old woman, a child ripped from her parents, a lovable zany killed by thugs, a nation herded like beasts to the slaughter: These are just a few of the show’s many tugs at our emotions. By the time we find Raisel in the Warsaw Ghetto, clutching a rag doll stained with the blood of a murdered Jewish friend, even the softest touch in the audience may grow wary of Dart’s hard sell. The People in the Picture reminds us of the Holocaust’s bitter injunction to never forget. It’s a worthy effort, but work this blunt can’t pierce very deep; the tears the show elicits are too easily wiped away.
