The list of things book readers hate about the Harry Potter movies is as long as the list of school supplies for a first-year student at Hogwarts. Although the films were generally well-received, the Harry Potter books inspired an intense fandom, and that’s ensured a certain amount of snobbery when it comes to changes made in the course of adaptation. What Harry Potter purists hate the most about the movies are the innumerable small changes, omissions, and embellishments that seem completely unnecessary to those who feel the original versions are perfect.
There doesn’t seem to be any particular film that draws more ire from Harry Potter purists, with all the movies in the series earning their fair share of criticism. Instead, fans seem to take umbrage (no pun intended) with the consistent differences that writers, directors, and actors chose to make for the sake of adaptation. To a dedicated book reader, these changes stand out like a troll in the dungeon.
The Omission Of The Marauders’ Backstory
Obviously, films don’t have as much time to play around with fun side stories as novels. Adaptations often have to cut a lot of background information and subplot from their storylines. This has happened quite a bit in the Harry Potter series, but Reddit user chaimahannachi thinks that the lack of a true backstory for the Marauders was the most glaring omission. The group, made up of James Potter, Remus Lupin, Sirius Black, and Peter Pettigrew, are the creators of the Marauder’s Map. Their friendship plays a very important role in the overall story of not only The Prisoner of Azkaban, but the entire series. Unfortunately, fans who only watched the film missed out on much of this personal history.
The Omission Of Voldemort’s Past
Although the Harry Potter books focus mainly on the story of their titular hero, the origin of Voldemort, who was once Tom Riddle, is also given plenty of attention. Book Six is devoted in great part to Harry and Dumbledore's journey through Riddle's past via memories. In the books, Harry finds out about the personal history of not just Voldemort, but his immediate family members, too. Reddit user morsmodre92 feels that the omission of all this additional info about Voldemort's past reduces him from how truly well-rounded as an evil villain he is in the books. The films make him less complex antagonist and more standard movie bad guy.
Ginny Weasley’s Lack Of Personality
In the books, readers watch Ginny Weasley develop into a strong, smart, and sassy young woman who was every bit Harry’s equal and the perfect romantic interest for him. According to many book fans, including Reddit user potatochops, those qualities don’t show up in the film adaptation of Ginny. Movie Ginny’s personality is seriously lacking, making it a bit of a mystery why Harry falls for her in the first place. The adapted version of Ginny lacks a lot of the agency and independence that the book version displayed.
The Low-Budget Triwizard Maze
In the novel Harry Potter and the Goblet of Fire, Harry and Cedric Diggory take on the final challenge of the Triwizard Tournament in the form of a gigantic maze. The book version of the maze is filled with all sorts of interesting things, like a riddle-spewing sphinx, a boggart, and even a blast-ended skrewt. None of these dynamic obstacles made it into the film adaptation. Instead, the maze was a fairly low-budget production with zero obstacles, featuring moving vines and little else to challenge the would-be champions. Readers were baffled that the film would skip over this final challenge in a rush to get to the film's climax in the graveyard with Voldemort.
