Duncan Jones' latest, Source Code, shares some thematic similarities with his striking 2009 debut, Moon--this film, it so happens, is also about an isolated guy who's at the mercy of technology and those who wield it--but it has little of the freshness and originality that made Moon remarkable. Despite a few creepy sci-fi touches, Source Code is a vague, competent, and utterly forgettable thriller. by Erik Henriksen
