Andrew Jacobs's documentary is a poignant portrait of a Jewish summer community in the Catskills (one of a few where once there'd been hundreds) peopled almost entirely by elderly concentration-camp survivors. Jacobs folds in aging snapshots and listens to the gray lions' stories and ends up mourning not only the losses of the Nazi rampage but also those of the post-war communal era, which is fading away into a second history as time presses on. Here's a full-bore "Jewish" cinematic feast, evoking in these old-timers' tales, inflections, and habits an entire century's worth of disappearing ethnic reality.
