The tagline of the new Will/Jaden Smith movie, After Earth, is: “Danger is real. Fear is a choice.” The movie, which was directed by the inexplicably still-working hack M. Night Shyamalan and based on a story devised by the elder Smith, hinges on the ability of its young protagonist Kitai (Jaden) to rid himself of fear so that he can defeat a giant, blind monster mole that hunts humans by detecting their anxiety.
