For ten years, the Harry Potter movies enchanted audiences across the globe. With eight movies, the series has more than enough time to squeeze in details from its source material. In fact, it had more time than most adaptations. Inevitably, however, some scenes, storylines, and characters didn't make the cut.

While the core elements of the story remain the same, fans have long lamented several glaring omissions that made the books so magical. Some of the movies bear more resemblance to their book counterpart than others.

Half-Blood Prince

The sixth installment of Harry Potter has a lot to juggle. As the series nears its finale, a lot of storylines – such as Voldemort's past, Harry's fate, and Dumbledore's role as a mentor – start to come to a head, resulting in one of Harry's most eventful years at Hogwarts.

However, the film doesn't feature the details needed for a lot of characters' motivations to make sense. Diving into Voldemort's past is the book's narrative core, but the film leaves out key memories such as the Gaunts and Hepzibah Smith. Ginny is also rendered two-dimensional in the film, as pretty much all of her character moments are removed – yet extra scenes, such as the attack on the Burrow, are added. The movie has a totally different tone as a result.

Goblet Of Fire

Goblet of Fire is by far the most pivotal of the Harry Potter movies, as it features Lord Voldemort's return and a darker, more threatening tone that sticks until the series' end. Harry faces greater challenges than he has before – but not all of them survived adaptation to the big screen.

The bulk of Barty Crouch's backstory is cut, making the Barty Crouch Jr. reveal confusing rather than shocking. Ludo Bagman doesn't get so much as a name drop and all of the house elf storylines featuring Dobby, Winky, and S.P.E.W. are ignored. And, of course, there's the infamous scene where Dumbledore throws Harry against a cabinet to confront him about putting his name in the Goblet of Fire – a move totally out of character for Harry's wizened mentor.

Deathly Hallows Part 2

For the most part, a lot of the final Harry Potter movie is similar to the book, such as Snape's death, breaking into Gringotts, and the epilogue. However, even splitting Deathly Hallows into two movies couldn't salvage every plot point.

Movie viewers don't get to hear the bulk of Dumbledore and Snape's backstories, which are such key parts of their character arcs. They also don't get to see the first kiss Ron and Hermione deserved – coming as a culmination of Ron's growing sensitivity when he tries to save the house elves. The most frustrating choices are neglecting to give Fred a proper death scene, Harry snapping the Elder Wand, and giving Voldemort a strange, supernatural death instead of dying the way he feared most: like a regular human man.

Order Of The Phoenix

As the longest book in the series, there was no way a completely book-accurate adaptation of Order of the Phoenix could've ever been made. However, it doesn't just leave out a lot of the book's content but also sets up a totally different tone.

Harry spends most of his fifth year in the books struggling emotionally, but every scene depicting his growing anger and frustration is cut (aside from one moment where he shouts at Dumbledore). Sirius is much more grounded and mature, despite his recklessness playing a huge part in his death. Also, a lot of details needed to contextualize later instalments  – such as Kreacher's betrayal, the explanation of the prophecy, and Mundungus Fletcher – are omitted.

Deathly Hallows Part 1

The first half of Deathly Hallows has a much slower pace than the other movies. That's not necessarily a bad thing; it makes for a much more atmospheric film, with the unsettling tension and frustration of the Horcrux hunt depicted particularly well. Dobby's death, Godric's Hollow, and the scenes in Malfoy Manor are also highlights.

But while the film hits most of the book's main beats, it does skip or alter some critical moments. The dance scene is a great addition, but it does mean that (like a lot of the movies) it emphasizes Harry and Hermione's friendship more than Harry and Ron's. Harry never has to watch Voldemort's full memory of killing Lily and James, and one of the darkest moments in the series - Wormtail being choked by his own hand after hesitating to kill Harry – is turned into a comedic moment.

Prisoner Of Azkaban

A lot of fans consider Prisoner of Azkaban to be the best Harry Potter movie – and for good reason. It's dark, quirky, and beautifully shot. It also faithfully honors the book in terms of both plot and tone.

Lupin, the Dementors, Sirius, time travel, and Harry's battle with his own fear are all masterfully done. The only important things the movie really skimps on are the full background details of the Marauders – namely why and how they became Animagi, and why Snape hates them so much – Harry's triumph in the Quidditch House Cup, and the toll the Time Turner and her fallout with Ron took on Hermione.

Chamber Of Secrets

Part of the reason why Chamber of Secrets clocks in as the longest Harry Potter movie is the fact it refuses to veer too far from the source material. The mystery over the Heir of Slytherin is unraveled in almost exactly the same way as the book, as is Harry's emotional rollercoaster and ostracization along the way.

Everything that is cut is extremely minor. The Deathday Party would've been cool to see onscreen, but doesn't add much to the plot. And while Percy's relationship with Penelope Clearwater and Filch's status as a Squib are interesting character details, it's easy to forgive the filmmakers for leaving them out.

Philosopher's Stone

The first Harry Potter movie is by far the most enchanting. Compared to Harry's other adventures, the stakes don't feel as high, and he's just as wonderstruck by Hogwarts, Diagon Alley, and magic in general as the audience.

Pretty much every character is written to be near-identical to the books – and pretty much every scene makes the script. The only big omissions are Harry and Malfoy's first meeting in Diagon Alley, their failed midnight duel, and some of the obstacles to the Philosopher's Stone. And, of course, everyone's favorite cut character: Peeves.
