007, Star Wars, and Star Trek movies, novels, and comics were able to produce sequels mainly because these works had a deep historical and cultural background, as well as a strong fan base, allowing the plot and characters of the works to continue and expand. The original works of these works all had complex worldviews and plots. The continuous addition of new plots and characters could make the story more colorful and attract more audiences. At the same time, the creative team of these works could also constantly excavate and create new characters and characters to make the story more interesting and fascinating. In contrast, although the Harry Potter series was also very popular, its story background and worldview were relatively simple, and the image of Harry Potter himself was relatively fixed. Therefore, it was difficult for the creative team to constantly introduce new plots and characters, resulting in a lack of continuity in the story. At the same time, the Harry Potter series also had some copyright and intellectual property issues, making it difficult for the creative team to freely create and sequels.
