The idea of a follow-up that doesn’t match a debut seems to be as old as the marketplace. Reasons differ. There’s hubris: In film we can think of Michael Cimino, who followed The Deer Hunter with Heaven’s Gate and went from a Best Picture Oscar to one of the biggest flops in movie history. Or a great first work can induce anxiety in a creator: After Invisible Man, Ralph Ellison never finished his decades-in-the-making second novel.
