Consider this “CSI: Riyadh.” After a bombing in an American residential compound in Saudi Arabia, the FBI sends in an investigation team whose greatest challenge isn’t the crime scene but the defensive Saudi officials who barely allow access to it. Director Peter Berg has a jittery, documentary style that heightens both the realism and the sense of panic, while Jamie Foxx has good chemistry with a hand-tied Saudi colonel (Ashraf Barhoum) who wants to help but can’t. The movie ends on a surprisingly bitter, cynical note – any American rah-rahs get shoved right back in your throat.
