There is much angst, handwringing and confessions throughout the 100-minute, intermission-less show, but Rebeck relies on too many heartfelt stories to move the action along. There just isn’t a lot of substance underneath the piles of dialog. You also wonder what has been happening in the many intervening years with the three individuals. Has Sam been estranged from his daughter? Has she been a constant presence in his life? Sam and Foster have known each other for over 30 years, but details emerge that such good friends would have known about each other. Director Moritz von Stuelpnagel does give Danny DeVito room to operate and his schtick can be quite hilarious as when he narrates a game of Sorry he plays all by himself. But even this scene, as inspired as it is, is overlong.
