The visual effects of the film were excellent, and the beautiful scenes presented a world full of magic and fantasy. In addition, the film also performed well in terms of music and acting, especially the performances of Daniel Radcliffe and Emma Watson. However, there were also some criticisms of the film. Some people thought that the story was a little dragged out and the plot development was a little complicated. In addition, there were some shortcomings in the film's description of the history of the magical world and the relationships between the characters, which might confuse some viewers. In summary, if you like the Harry Potter series and fantasy movies and have certain requirements for visual effects and storylines, I would suggest that you watch it. However, if you were more cautious about such movies or didn't like complicated plots, then you might not be suitable to watch them.
