research of thriller genre

I researched into what the thriller genre is all about and my search result came out with the explanation that a Thriller is a broad genre of literature, film, television, and gaming that includes numerous and often overlapping sub-genres. Thrillers are characterized by fast pacing, frequent action, and resourceful heroes who must thwart the plans of more-powerful and better-equipped villains. But as thriller is such a broad genre I wanted to specialize in a certain sub genre of a thriller and this is when looked into different types of a thriller and came up with the idea of a psychological thriller as it would add to the aspect and weirdness of my film. A Psychological thriller is a specific sub-genre of the wide-ranging thriller genre. However, this genre often incorporates elements from the mystery genre in addition to the typical traits of the thriller genre. Also, occasionally this genre will border into the also wide-ranging Horror genre. In conclusion I believed this sub genre of a thriller fitted best with my film idea as it would link in with the mystery and horror genre as well as mainly focusing on the thriller genre.
