Playwright Glen Berger said something to the Seattle Times that lucidly explains his flummoxing O Lovely Glowworm: "My favorite parts in Shakespeare are like when Macbeth learns his wife is dead and launches into the speech about 'tomorrow and tomorrow and tomorrow.' Suddenly you're 50 miles above the earth, looking down at these tiny lives from a new perspective." Glowworm, which takes place in the mind of a dead goat who just wants to be in a Nativity scene, is like a two-and-a-half-hour "tomorrow and tomorrow and tomorrow" speech—except with Irish soldiers, a mermaid, love triangles, and a wistful taxidermist.
