“Silencer” (*1/2 out of four) was a boring action thriller that fires all blanks about a retired hitman (Johnny Messner) who is called back into action when his former employer (Danny Trejo and Robert Lasardo) threaten him and his family which leads to an all-out war along the Mexican border. Molasses-moving movie just about cries out for Sam Peckinpah in his prime. Trejo can play this role in his sleep by now (and often does) and Messner practically seems asleep in his lifeless performance.
