Thriller: Top Favourite Genre

Since Thriller is one of my top favourite genres, I had my good share of it and I still can't get enough. This list will only contain films since there aren't many dramas under this genre. I also wanted a pure films' list. The majority of the list will be South Korean films since I love their thrillers the most. There are Japanese and Chinese films as well only not as many as Korean ones. Only the first 10 titles are in order.
