Officers Taylor and Zavala (Jake Gyllenhaal, Michael Pena) are good friends and valiant protectors of the people. Episodically, the movie follows them as they crisscross paths with an encroaching drug cartel and its street soldiers. Many dead bodies and grisly sights ensue. Taylor falls for the newfound love of his life, played by Anna Kendrick. Shot in relentless first-person style, the film is like Xbox reconfigured for the movies. There is plenty of suspense here, but not the strongest.
