In his first directorial effort without his twin brother, Allen Hughes roots down into urban vice and sullied power corridors with Broken City, a muscular but middling thriller of sprawling political corruption whose reach exceeds its grasp. Starring Mark Wahlberg as a crusading, recovering alcoholic ex-cop gunning to bring down an ethically questionable mayor of New York City (Russell Crowe), the movie is gritty but narratively unconvincing in wide swatches, succeeding in tone and atmosphere more than the specifics of its conspiratorial plotting.
