What’s the old expression about putting lipstick on a pig? “2 Guns,” a busy and bullet-riddled new action movie, has some mighty fine lipstick, but it’s still a porker and it wallows in the same old dirty water.
It takes a while to notice, though. Based on a graphic novel by Steven Grant and shuttling between both sides of the US-Mexican border, “2 Guns” stars Denzel Washington and Mark Wahlberg as Bobby and Stig, a raffish pair of drug dealers who, unbeknownst to each other at first, are both undercover cops, Bobby for the Drug Enforcement Administration and Stig for Navy Intelligence. Trust me, it gets more complicated, and quickly.
