Thriller Opening Sequence

My opening sequence will be a thriller. The reason is because the ghost will not be fully appearing into the movie until the later scenes. I had planned to make the movie more psychological in the beginning to get the viewers more intrigued and into the movie. Thrillers can also conclude suspense and action while still having that needed tension for the movie. It will also be easier to produce if I go with the correct pitch. This genre would be able to give me a way to cut the movie perfectly while still being able to make the audience want more. Thriller is also a genre that has it's own guidelines that could fit and be combined with other genres as a subgenre for movies.
