Flickering TV Inside House (spoiler)
At the end of her escape, Elena closes in on a house with a TV flickering through its window; and the scene looks realistic _except_ the light of the TV is greatly emphasized. Perhaps because I'd just listened to a review of a Cuban "zombie" film, my first thought was Elena was escaping from one kind of psychic prison (her cubicle and the ubiquitous pyramidic crystal) to another kind of psychic prison (being a couch potato watching TV in suburbia). But on second thought, such an interpretation seemed too pat and silly, and in general a little too precious.
How did you interpret Elena confronting the flickering light of a TV inside a tract house as soon as she completed her escape?
