‘Grand Concourse’ at Steppenwolf: Soup’s on, but it’s boiling over with angst, anger and evil

Review: The fascination of Heidi Schreck’s play “Grand Concourse,” now at Steppenwolf Theatre, lies not so much in the personal crisis of a nun whose faith is wavering as it is in the human response of a good person directly affected by unmitigated evil. That moral dilemma keeps us hanging on through the last syllable, or rather sigh, of this well-made drama. ★★★
