One movie that clearly fails to live up to Rowling’s work is the sixth installment in the series, Harry Potter and the Half-Blood Prince. This book is ranked #1 out of all seven books, though it’s only #5 on our list of movies. The Goblet of Fire movie also left fans of the books feeling cold, ranking at #2 on the list of books, but #6 on the list of movies. Prisoner of Azkaban is high on both lists, but as the #1 movie with 72% upvotes, its film version is beloved slightly more than the book, which is #3 on its list with 70% approval.
On the other side of the spectrum are movies that fans love more than the books. Chamber of Secrets is #4 on the movie rankings (though it’s switched spots with Sorcerer’s Stone twice the week of publication), upvoted by 67% of voters, but it’s in last place on the list of books. Deathly Hallows is a complicated comparison, since there are two movies to one book. Part II is all the way up at #2 on the list of movies, markedly better than the book’s #5 ranking. Meanwhile, Part I is in last place among the eight films based on the book series, placing it well behind its source material.
