“Mercury Plains” (*1/2 out of four) was a tired, boring Redbox thriller about a brave drifter (Scott Eastwood- son of Clint) who runs away to Mexico and joins a paramilitary group fighting the drug cartels but he soon gets swept up in a personal war against one of the drug cartel members (Nick Chinlund) and begins to question their motives. Eastwood who was last seen in Nicholas Sparks’ “The Longest Ride” is a promising actor but you’ll eventually get numbed by all the sleaze. Later scenes involving shootouts and chases through the desert cry out for Sam Peckinpah in his prime but unfortunately there’s no “Wild Bunch” here.
