Like so many movies about police, this chest-thumping cop opera seems less concerned with their actual lives than with how we want to feel about them: for law-and-order conservatives, there's the usual huffing about the thin blue line, topped off by the obligatory funeral with bagpipes; for bleeding-heart liberals, there's a righteous cop (Edward Norton) making a lonely and principled stand against corruption in the department. Director Gavin O?Connor (Miracle) intended this as an homage to his father, a New York City police detective, and collaborated on the story with his brother, Gregory, and NYPD officer Robert Hopes. But the finished product, amped up by macho screenwriter Joe Carnahan (Narc, Smokin' Aces), is the sort of brutal, lumbering, and cliched thriller that only widens the divide between police and those they protect. With Jon Voight, Colin Farrell, and Noah Emmerich. R, 125 min.
