Investigation of genre

To investigate we watch the openings to horror films for example paranormal activity and scream etc. I decided that there are two types of horror film, the first type was the classic old fashioned jump scare film and then the more modern horror film when the opening is very subtle beginning. The old fashioned films have the un realistic jump scares at the beginning etc. One of the films i researched was paranormal activity this had a very subtle beginning and was mostly just setting the scene and introducing the film. They had certain conventions used to foreshadow and hint that the film is a horror. This made the film intriguing and makes the audience feel like they want to watch more and find out the rest of the story.
