There were several possible reasons why novels adapted into movies were more popular: 1. Visual presentation: A movie is a visual art form that can be directly watched to bring a more intuitive feeling to the audience. Movies could present the plot and characters in novels in a more vivid, three-dimensional, and dynamic way, making it easier for the audience to resonate and emotionally invest in them. 2. The story's appeal: Movie adaptation would usually cut and adjust the plot and characters of the novel to better suit the narrative and visual effects of the movie. Therefore, the adapted movie might be more compact, exciting, interesting, and easier to attract the audience's attention and interest. 3. Audience: The adapted works usually target a wider audience, including young audiences, family audiences, business audiences, and so on. These audiences might be more likely to accept the storyline and characters in the movie because they were easier to understand and empathize with. 4. Film publicity: The release and promotion of the film can attract more audiences, including through television, the Internet, social media and other channels for publicity and promotion. The film adaptation might be more easily exposed and recommended by these channels to attract more potential audiences. The popularity of novels adapted into movies could be due to the visual presentation of the movie, the appeal of the story, the audience, and the publicity of the movie.
