Harry Potter and the Philosopher's Stone
The Good: The casting. Dan had an allergic reaction to the green contact lenses he was asked to wear, so Harry's eyes in the film are blue. And we can't help thinking Emma Watson's modelling agent is grateful that she wasn't forced to wear fake gnashers for Hermione's buck teeth. Rupert Grint isn't lanky tall like Ron in the books.
The Bad: A sequence involving Ron's brother Charlie, who's drafted in to help get Hagrid's dragon Norbert out of Hogwarts, is missing. In fact, Charlie was never even cast in the film adaptations. Scenes with the poltergeist, Peeves, were shot (with Rik Mayall), but never made the final cut.
Harry Potter and the Chamber of Secrets
The Good: When they drink Polyjuice potion, the filmmakers niftily made Dan and Rupert's voices come out of Crabbe and Goyle. This detail wasn’t in the book, and made the scene both funnier and less confusing. They repeat this trick in ‘Deathly Hallows’.
The Bad: This book ends with a giant party; altogether more fitting than director Chris Columbus's saccharine round of cheering and happy news.

Harry Potter and the Prisoner of Azkaban
The Good: Director Alfonso Cuaron brought a few of his own idiosyncrasies to JK Rowling's world, most notably including shrunken heads throughout the flick. And then there's Professor Flitwick's frog choir, which sings a John Williams-penned song.
