I don’t remember feeling the weight of that insight, or for that matter, the levity of the jokes, when I saw the 2007 production. Part of the improvement in this revival is, no doubt, the result of cuts, fine-tuning and rewritten scenes. The elimination of the intermission helps too; the two halves of the story don’t separate like a sauce. And there’s something to be said for the way a Broadway house, when a solid play is sized up to suit it, responds by giving it space to breathe.
