The title sequence of Stranger Things uses multiple close-up shots of letters that come together like a puzzle to mirror the mystery genre. The opening scene establishes a sense of location with shots of an abandoned building and woods to set up danger. Sound design uses diegetic alarms and footsteps to create panic during the scientist's run and non-diegetic music to build tension as the boys enter the woods alone. Costumes and props are used to represent the characters and set up their innocence against the looming threat.
