2 DAYS IN NEW YORK Actress-writer-director Julie Delpy’s follow-up to 2007’s“2 Days in Paris” is an engagingly sloppy comedy about the ways our families drive us nuts. Chris Rock is the movie’s secret weapon as the star’s long-suffering boyfriend enduring a visit from her boorish French relatives. (Magnolia, $26.98; Blu-ray, $29.98)
