Distasteful though that is, it’s good drama, and 'Ghosts' remains a provocative, engrossing work, to which O’Brien’s production does justice. It also does justice to the idea of provocative, engrossing work in the first place. 'Ghosts' is the 14th and presumably final collaboration between O’Brien and André Bishop, Lincoln Center Theater’s producing artistic director, who is stepping down at the end of this season after 33 years with the company. Their notable productions of Hellman, Stoppard, Shakespeare and others have earned them this warm valedictory moment. And yet not totally valedictory. As 'Ghosts' demonstrates, men’s imprints do not fade so easily. And nothing is ever as haunted as a stage.
