The document discusses how the filmmakers addressed their audience and created tension and mystery. They used a female main character as the villain to subvert expectations that the villain would be male. Both key scenes took place in middle-class locations, like a house and coffee shop, to make the audience feel they could relate to the settings. In the house scene, low lighting and contrast created a dark and scary atmosphere, while the well-lit coffee shop provided relief but also intrigue by showing the villain in public. A kitchen knife rather than a gun was used as the weapon to make the killing of a child seem more realistic given the suburban setting.
