“The Poker Night” was once the working title for what would become Tennessee Williams’s most celebrated work. So perhaps it’s appropriate that a poker game provides one of the few moments approaching excitement in the torpid revival of the play that was renamed “A Streetcar Named Desire.” ...when the woman in the seat beside me started to nod off during the first act of this “Streetcar,” I didn’t have the heart to nudge her. Handsomely designed by a top-flight team — including Eugene Lee (set), Paul Tazewell (costumes) and Edward Pierce (lighting) — this “Streetcar” is mostly an exquisite snooze.
