Some Harry Potter movies are a lot easier to rewatch than others. I've probably only watched both of the Deathly Hallows movies twice in my life, while I've watched Harry Potter and the Prisoner of Azkaban more than I can count. I suppose it's easier to rewatch the movies that make Hogwarts feel like a familiar, homey environment as opposed to a deadly battleground overtaken by Voldemort. Additionally, some Harry Potter movies are objectively better than others, which is okay! Alfonso Cuarón made a masterpiece with Prisoner of Azkaban, while Chris Columbus made an okay recreation of the book with Harry Potter and the Chamber of Secrets. What I'm trying to say is it's okay if you don't love all Harry Potter media equally. The Fantastic Beasts Movies are an affront to all that is good about the OG series, and believing that does not make you a fake fan.
