Here's Denzel Washington in action-hero mode, and Mark Wahlberg in funny-dopey sidekick mode, and Edward James Olmos deliciously slumming his way through a role as a Mexican drug kingpin named Papi, and Bill "Knuckles" Paxton showing up in a few scenes making crazy eyes. There are some cool car chases, a bunch of shooting, a bank robbery, and plenty of quipping. This is all 100 percent fine. But for a B movie that revels in being empty-headed, 2 Guns still comes up a little empty-handed. Even the title smacks of laziness, but it's the absolutely ludicrous plot that hobbles what could have been a fun, thoughtless, chewy genre exercise. by Ned Lannamann
