This question involved the marketing strategy of the novel and movie, the audience, and the word-of-mouth evaluation. It was impossible to give a simple affirmative or negative answer. However, this problem could be discussed from some angles. The novel and the movie were two different art forms. Their audiences and ways of expression were also different. If the film adaptation of the new series of novels was more popular than Harry Potter, it might be because the film attracted a wider audience in terms of visual effects, plot arrangement, and character creation. These audiences might prefer this kind of visual and plot experience rather than traditional novel reading. On the other hand, if the quality and reputation of the new series were better, it might gain more recognition and praise from readers because of its outstanding storyline, deep thinking, and character portrayals. These readers might prefer the print or e-book version of the novel and spend more time reading it. The marketing strategy for novels and movies was also very important. If the new series could make full use of the marketing methods of the movie, such as cooperating with related brands, using social media to promote, and carrying out marketing activities, it might also gain more advantages in the promotion of the movie. In summary, if the movie adapted from the new series of novels was more popular than Harry Potter, then the novel might beat Harry Potter because of its better storyline, deep thinking, character descriptions, and so on. However, many factors had to be taken into account, including the quality of the novel and movie, word of mouth evaluation, marketing strategy, and so on.
