Aaron Johnson (Kick-Ass) and Taylor "The Kiss of Death" Kitsch (John Carter, Battleship) star as a pair of easygoing, Southern California pot farmers who run afoul of some nasty Mexican drug lords. The bad guys (led by Salma Hayek) kidnap Blake Lively ("Gossip Girl"), the shared girlfriend of our two anti-heroes. In response, our boys weapon up and go gunning for revenge. Oliver Stone directs with nearly the same manic energy he used in Natural Born Killers. Actually, it's kinda nice to see the return of the bloody, sleazy, old-school version of Stone. 130 minutes R.
