If Journey to the West was completely based on the original work, it might be a very classic and interesting movie or TV series. The following are some possible changes: 1. Character setting: There are many character settings and plots in the original novel that are inconsistent with modern society. For example, Tang Sanzang is a Buddhist monk instead of an ordinary person; Sun Wukong and Zhu Bajie are two monsters of different races instead of humans; Sha Wujing is a desert god. If they were to follow the original work, the setting and background of these characters might be even more complicated and mysterious. 2. Plot: The plot in the original book is very compact and interesting, but it may be difficult to show all the plot in the movie if it is completely shot according to the original book. Because many of the passages in the original novel were Buddhist stories, which were not accepted in modern society, the film or TV series might be cut or changed to suit the tastes of modern audiences. 3. Special effects: There were many special effects in the original novel that were not realized, such as the transformation and flight of monsters. If it was shot completely according to the original work, it might need to use more advanced technology to create special effects to ensure the quality of the movie or TV series. 4. Language: The language used in the original work is a kind of ancient language. If it is completely shot according to the original work, the language may need to be adjusted to ensure that the audience can understand the plot and dialogue in the movie. If Journey to the West was shot according to the original work, it might be a very classic and interesting movie or TV series. However, the original work needed to be adjusted and deleted appropriately to ensure that it met the tastes of modern audiences.
