Smartly, Stoppard did not write Leopoldstadt as a Holocaust play. Impending doom lurks in Adam Cork's chilling score, but otherwise, the show is a lively, rich family drama. We're invited into the Merz-Jacobowitzes' commonplace gatherings, debates, trysts, squabbles, and playtimes as though we, too, are kin. There's a healthy helping of intellectual talk — Stoppard's specialty — but it's not esoteric, and in the hands of a superb Brandon Uranowitz, who gets to philosophize the most as the mathematician Ludwig, it's endlessly captivating. Plus, subjects like math are just as often the butt of jokes, of which there are plenty. Stoppard also warms us up to the characters with his trademark witty humor; a misunderstanding between a circumciser and a cigar cutter even provides a full-blown laugh-out-loud moment.
