Online novels couldn't simply be described as moving forward or backward. Although the development and popularity of online novels had promoted the progress of the film and television industry, there were also some negative effects. The popularity of online novels provided a lot of material and inspiration for the film and television industry. Many online novels were adapted into movies, TV series, animations, and other film and television works. These works might have unique storylines, characters, and worldviews. If they were not well performed and presented, it might have a negative impact on the quality of the film and television industry. The content of some web novels may be too violent, bloody or sensitive. If they are brought to the silver screen, it may cause dissatisfaction or discomfort among the audience and negatively affect the quality of the film. The release of online novels on the silver screen also promoted the development and spread of online novels. By adapting online novels into films and television works, more people could appreciate the plot and characters in the novel, and at the same time, more people could understand the meaning and style of online novels. To sum up, there were both positive and negative effects on the film and television industry when online novels were brought to the silver screen. But no matter what, the development and popularity of online novels have promoted the progress of the entire cultural industry and provided us with more creative inspiration and entertainment choices.
