A thriller is a genre of film that uses suspense, tension, and excitement to stimulate the viewer's emotions. Key elements of thrillers include an adrenaline-pumping narrative pace, obstacles for the protagonist to overcome, and a villain-driven plot. Successful thrillers typically feature a protagonist facing death or danger, an initially stronger antagonist, a mystery that must be solved, scenes from the protagonist's point of view, and realistic representations of action and characters. Common themes in thrillers are the desire for justice and individuals' sense of morality in a corrupt world.
