You'd think poor, bedraggled cop John McClane (Bruce Willis) would be tired of saving the world by now, but no. NYC's favorite supercop returns for the fourth time. For this outing, he's teamed up with the kid from the Mac/PC commercials (Justin Long) to defeat a cabal of Internet-based terrorists who are systematically shutting down the United States. Those looking for action will get their money's worth. 130 minutes PG-13.
