Tasked with clearing out their late grandmother’s house in Hillside, New Jersey, siblings Elan and Jonathan Bogarín approach the chore as if they were archeologists, sorting through the woman’s possessions to see what they reveal about middle-class Jewish-American life from the mid- to late-20th century. This experimental documentary (which the siblings also directed) traces their progress in both practical and philosophical terms, with fun tableaux of the grandmother’s stuff and provocative interviews with various professionals (a physicist, a historian, an archivist) who muse on what the Bogaríns’ endeavor might teach us about civilization. The siblings exhibit much as curiosity about cinematic form as they do about their family history; the film is a surprising melange of found footage, playful montages, choreographed routines, and dramatic reenactments. Not all of devices work (some passages border on cloying), but on the whole this evokes a pleasant sense of wonder about everyday life.
