The thriller genre does exactly what its name says it will do; it thrills the audience. Thrillers are meant to captivate the audience with a gripping storyline that keeps viewers on the edge of their seats. Every moment should be exciting, in the sense that the viewer is always drawn to the world of the movie for one reason or another. The story should be intriguing enough that you simply have to pay attention to nothing else but what's unfolding on the screen in front of you. Whether it's because the story is action-packed, the characters are multidimensional, or the plot is complex, a thriller should keep its audience fully invested.
