The document discusses various horror movie subgenres and their common conventions. It provides descriptions of supernatural, slasher, possession, psychological, and gothic horror genres. It notes that the group chose to focus their promotional package on psychological horror since it allows more creative freedom than other subgenres with stricter conventions. They believe this will help them develop a fresh, original idea that stands out from current popular supernatural and possession movies. Their goal is to create a psychological horror film that becomes a cinematic classic like Silence of the Lambs and Gothika.
