The main reasons why movies adapted from famous works were easy to fail were as follows: 1. The cultural background and atmosphere of the original work is different from that of the adapted work. A famous work usually reflects a certain cultural background and atmosphere, while an adapted work needs to consider whether the cultural background and atmosphere behind the original work is consistent with the adapted film and television work. If the adaptation was not done properly, it might cause irrationality in the character setting, plot setting, theme expression, and so on, which would affect the movie's viewing experience. 2. The plot of the original work is complex and the structure is compact: masterpieces usually contain very complicated plots and structures such as multi-angle love, suspense reasoning, historical events, etc. The adaptation required a reorganization of the original work so that the film could smoothly digest and express these complex plots and structures. If the adaptation was not done properly, it might cause the structure of the film to be chaotic, and the logic would be incoherent, affecting the viewing effect. 3. The quality difference between the adapted works and the original works: The quality of the masterpieces is very high, and they contain profound thoughts and philosophical meanings. The adaptation required an in-depth analysis and excavation of the original work so that the film could better reflect the original work's ideology and theme. If the quality of the adaptation was not as good as the original, it might cause the film to lose its appeal. 4. The influence of the adapted works and the original works: The influence of the famous works is very large and has become a cultural classic. The adaptation needed to consider whether it would affect the influence of the original work and how to balance the relationship between the adaptation and the original work. If the adaptation was too faithful to the original work, it might reduce the influence and market competitiveness of the film. Movies adapted from famous works were easy to fail because they needed to analyze and adapt the original works in depth. At the same time, they needed to consider the cultural background, plot structure, quality, and influence of the film.
