The Shakespeare tragedy that gave us the expression “How sharper than a serpent’s tooth it is to have a thankless child.” has not one but two ungrateful children, and it’s especially galling because he turned over his entire kingdom to them. Paul Scofield is an ancient, imposing shell of a Lear tormented by his too-long life as well as by daughters he calls “unnatural hags.” At one point, the king looks his eldest daughter, Goneril (Ireme Worth), straight in the eye and declares, “Thou art a boil, a plague-sore, of embossed carbuncle in my corrupted blood.” These are the troubles not even the best-trained family counselor could ever hope to resolve.
