The message of this slow-paced and philosophical film, directed by Oday Rasheed and set in post–Mission Accomplished Baghdad, is simple and profound: War does not produce heroes; it produces serial killers. In Qarantina, the serial killer—a thirtysomething man who initially murdered people for political reasons but now murders people for no reason—rents a room from a vulnerable family. He bullies the impotent husband, fucks the love-starved wife, and mocks their son's attempts to return to school and a normal boyhood. There is no joy in this home, or the city, whose bullet-ridden streets are patrolled by American tanks. Indeed, this is a great place for serial killers.
