Excerpt from The Good, the Bad, and the Ugly: Questioning the “Greatness” of William Shakespeare
Dilbert Terrell

IV. Shortly after his blockbuster success with the early history/tragedy Richard III, Shakespeare wrote his greatest plays, the ones everyone knows, at least by title: Julius Caesar, Hamlet, Othello, Macbeth, and King Lear. But great as these plays are, they too often have weak spots. Hamlet, as any director will tell you, is far too long—the longest play Shakespeare wrote and is full of digressions and long topical speeches that are incomprehensible to anyone but a person of Shakespeare’s day and age. Julius Caesar loses all its plot momentum in the third act after its title character is killed. Pick any traditionally “great” Shakespeare play, and you’ll run across some stumbling block to its greatness somewhere.

V. Sometime after composing King Lear, Shakespeare’s poetic powers began to weaken. He grew tired of all the genres he’d triumphed over—comedy, history, and tragedy—and tried to experiment with new forms of theatre. Some critics call them “tragicomedies”; others “romances,” and still others just call them “problem plays” because they are, for lack of a better word, just plain “weird.” These plays are so strange that most people don’t even recognize the titles as something Shakespeare wrote: Timon of Athens, Pericles, Cymbeline, Coriolanus, and others.
