In Christian Petzold's film 'Yella', a young woman stalked by her husband after leaving him slowly rebuilds her life, and self-respect, through starting a relationship with a criminal businessman. But it's not clear how much of the story is real, and how much is the product of her traumatised mind. In its conclusion, the film resolves this question, and the answer is almost inevitably disappointing; the kick in the tail insufficiently surprising or satisfying. What is good, however, is most of what precedes the ending, as the viewer is drawn into a world intriguingly on the balance of normalcy and the sinister, as seen by a woman herself on the edge. It's nicely underplayed and there's scarcely a wasted scene; it's just a shame that the final resolution has little new to add.
