The big-screen version of inventor Robert Kearns' legal battles with Ford and Chrysler — both of which nicked his intermittent windshield wiper without giving him credit, much less paying a cent — is about as exciting as Kearns' Wikipedia entry. You know how it ends — Hollywood doesn't make movies in which Goliath trounces David, especially when he's Greg Kinnear (usually kinetic, really dull here) — so all you're left with are windshield wipers going back and forth ... and back and forth ... and back and forth.
