Films tend to confirm, not confront, stereotypes. Not so Israeli director Rama Burshtein’s exquisitely acted, radiantly shot, and delicately nuanced “Fill the Void,” a melodrama set in the ultra-Orthodox Haredi Jewish community of Tel Aviv. By bringing to life complex and sympathetic characters in a precisely observed setting and social framework, and by presenting that isolated world as a microcosm, Burshtein has achieved a gripping film without victims or villains, an ambiguous tragedy drawing on universal themes of love and loss, self-sacrifice and self-preservation.
