Resolutely non-confrontational, Andrew Bovell, author of When the Rain Stops Falling (Newhouse Theater), spends astonishing amounts of stage time dodging his story's central dilemma, about the damage fathers do to sons and its possible repair. An elaborately layered puzzle, leaping across decades from one set of characters to another, its scenes full of ingenious verbal echoes, Bovell's script is enormously clever—"too clever by half," as the British say. His efforts to avoid supplying key pieces of information may mislead you into thinking that his central events don't make sense, or cause them to strike you as hopelessly contrived. David Cromer's direction, locking tautly into Bovell's ornate setup, gets solid performances, particularly from Kate Blumberg and Richard Topol. But the constant downpour of Bovell's ingenuity dampens the good they do.
