When a play opens on a man’s hospital deathbed there isn’t a transparent opportunity for comedy readily available. In a different work, perhaps, the undeniably grim theme of death would have been spun into sugar by the power of love or given supposedly weighty significance by various characters’ profound reflections on human mortality. But The Lyons, Nicky Silver’s play centering on family dysfunction, which opened on March 27 at the Santa Fe Playhouse and will continue to run through April 13, isn’t a play about people with delusions of idealistic outcomes.
