The main reason why the TV series adapted from the novel was not as smooth and complete as the original was that the adaptation process might face many challenges. The following are the reasons why the TV series might not be as good as the original: 1. Extinction or addition of plots: During the adaptation process, important plots in the original work may be deleted or added to the TV series. This might cause the audience's evaluation of the TV series to drop. 2. Changing the image of the characters: During the adaptation process, the image of the characters in the novel may be changed to make them more in line with the style and character setting of the TV series. This might cause the audience to be confused about the character's image and affect their understanding and feelings of the plot. 3. Changing the rhythm and narrative: The adaptation process may change the rhythm and narrative of the novel to make it more in line with the rhythm and narrative of the TV series. This might cause the TV series to have a different narrative from the original, confusing the audience. 4. Financial and resource constraints: During the adaptation process, the quality of the adaptation may be reduced due to financial and resource constraints. If the quality of the adaptation was not good, the TV series might not be as complete and smooth as the original. 5. Different target audiences: The target audiences of the novel and the TV series may be different, resulting in the plot and character setting of the TV series being different from the original. This might cause the audience's evaluation of the TV series to drop. Therefore, the above factors needed to be carefully considered during the adaptation process to ensure the quality of the TV series.
