The narrative style of a movie refers to the way the movie tells the story. It can include various elements such as plot, characters, scenes, dialogue, perspective, etc. But the most important thing is to let the audience understand the core and theme of the story. Different narrative styles can produce different effects. For example, suspense movies usually use tight plots and tense atmosphere to attract the audience's attention, while romantic movies usually use warm, lyrical scenes and dialogue to convey emotions. Different narrative styles can also have different effects on the production and box office of a movie. Therefore, directors and screenwriters usually try different styles to create the most attractive and successful movie.
