When you bring home a war movie that stars a professional wrestler, you’re prepared to watch a meathead special. Not so with “The Wall” (2017). About two minutes in, I got the sense this was going to be some kind of throwback drama, like a teleplay from 50 years ago or a short story from even longer ago. (The fact the wrestler doesn’t have a lot of dialogue helps.) An Army Ranger and an Iraqi jihadist square off physically, technologically and psychologically, but the story could have just as easily been set in World War II or the Civil War.
