The opening sequence uses mise-en-scene and editing to establish conventions of the horror genre. Various shots introduce characters surrounded by candles in a dark room filled with religious and family images, creating an ominous and gloomy atmosphere. Within the first 40 seconds, the editor introduces each character individually to show their emotions and worry as tensions rise during a family meal, hinting at isolation and lack of true connection between some of the characters. Overall, the shots, lighting, and editing aim to set an unsettling and tense tone typical of horror films through visual and character details.
