Despite some unconventional costume choices, most elements of the film opening conform to thriller genre conventions. The dingy alleyway and garage settings establish a creepy atmosphere similar to other thrillers. Dexter, the mysterious kidnapper, is dressed entirely in dark clothes keeping with expectations. His identity remains unknown, also typical of the genre. Sudden intense music and Sarah's imprisonment further signal this is a thriller. Camera shots and editing maintain a disjointed yet exciting pace. The dark title graphics with fading grey letters conform to the sinister thriller tone expected by audiences.
