“Man Down” (*** out of four) was a heartfelt and affecting story of a U.S. marine (Shia LaBeouf) who returns home from Afghanistan but finds he is physically and emotionally unable to return to the life he left behind with his wife and son. A flawed but still compelling look at PTSD and how the brutality of war often affects soldiers long after they return home. LaBeouf sears the screen in one of his most powerful performances. Gary Oldman is strong also as always in a key supporting role.
