Despite its state-of-the-art computer graphics and eye-catching special effects, Minority Report is basically a chase movie built on a question—one that Charles Dickens explored in A Christmas Carol. Dickens's Ebenezer Scrooge asks the visiting spirits if his foretold future of loneliness and gloom is how things "will" be, or how they "might" be. In Dickens, the answer is that Scrooge can change the late-night prophecy. (Why else would the spirits be visiting him, he correctly surmises.) In Minority Report, the answer is a bit cloudier, which makes the tale a lot more frightening.
