"Hamlet' dwarfs 'Hamilton' - it dwarfs pretty much everything - but there's a revealing similarity between them. Shakespeare's longest play leaves its audience in the dark about some basic and seemingly crucial facts. It's not as if the Bard forgot, in the course of all those words, to tell us whether Hamlet was crazy or only pretending: He wanted us to wonder. He forces us to work on a puzzle that has no definite answer. And this mysteriousness is one reason why we find the play irresistible.
