2 Guns is the sort of movie they don't make much anymore, which I imagine will get it praised more than it should. A dark, down-and-dirty B-movie thriller, the film stars Denzel Washington and Mark Wahlberg as tough-talking law enforcement officers -- one DEA, one Naval intelligence -- that have to square off with crooked cops and scary drug lords. Proudly rated R, 2 Guns is as nasty as it wants to be. Is that enough? I reviewed the film for Screen International.
