This film cracks the puzzle of making a dreamy, surreal and non-chronological narrative engaging. In this regard it uses similar devices as Mulholland Drive and Repulsion - yet it is far from a simple clone. Most importantly it has convincing portrayals of the three significant protagonists (great acting by all 3) and a winning combination of setting and soundtrack. At a deeper level, it successfully conveys the twisted but coherent logic employed by the lead as she struggles to attain a sense of security. The audience is encouraged not to be sympathetic but cognisant of the thinking which leads Janie down her narrative path.
