“Jarhead: Law Of Return” (**1/2 out of four) was a mildly engrossing action melodrama about a fighter pilot (Devon Sawa) for the Israeli Defense Forces and son of a U.S. senator (Robert Patrick) who is shot down behind enemy lines and a squad of top-ranked soldiers must risk their lives to get him back. Fourth entry in this series is well-directed by action veteran Don Michael Paul who knows how to stage and shoot action scenes but story and script gradually feel hollow after a while. Still, though, you have to give this ongoing series credit because all of its entries are better than the original.
