Which two genres are co-dependent?

Two genres that are often considered co-dependent are Horror and thriller. Horror relies on the build-up of tension and suspense to evoke fear, while thrillers typically focus on fast-paced plots and unexpected twists that keep the audience on edge. The elements of suspense and psychological tension in thrillers enhance the horror experience, making the two genres frequently intersect in films and literature. Together, they create a more intense emotional experience for the audience.
