Fatih Akin, the German filmmaker of Turkish heritage, has carved a niche making provocative films that navigate the experience of other German Turks. In this drama, Akin intertwines two narratives, each set in both northern Germany and Istanbul, and featuring the troubled adult children reacting to the "sins" of their parents, to examine the uneasy, but not irreconcilable conflicts between countries and generations. Much of the plot relies on contrivance, but earnest intentions, fine performances and a nonlinear style add up to an affecting feature. In English, and German and Turkish, with subtitles.
