LOSER — David Mamet: It’s been an annus horribilis for one of America’s greatest living playwrights. “The Anarchist,” his new meditation on morality and politics, opened to scathing reviews. It closed on Broadway just two weeks later, despite the combined star wattage of Patti Lupone and Debra Winger. An Al Pacino-led revival of “Glengarry Glen Ross” remains a hot ticket, but critics hate that one too.
