Audience expectations from our film genre

For our film genre we have chosen to do a horror film. We are going to use the typical horror conventions such as dark lighting, mysterious characters and fast camera shots. As our film introduction only gives away small details of the plot, we expect the audience to be oblivious to what is about to unfold and maybe a little confused. We are hoping that the film will make the audience feel scared and on occasion make them jump. These are obviously very important traits in a horror film, but are not always easy to achieve.
