Horror films commonly feature certain iconography like weapons and dark costumes. Settings typically include family homes to enhance realism or abandoned places to build suspense. Character archetypes include the villain, a character who dies while solving a problem, and one who survives to defeat the villain. Themes revolve around dark and gruesome atmospheres that scare audiences by showing the consequences of characters' mistakes. Narratives usually follow a pattern of establishing a threat, characters attempting to defeat it through trials, and the threat ultimately being vanquished, though some films subvert this by having the villain win. Stylistically, horror uses ambient sounds and little lighting to unsettle viewers.
