Warner Bros is in talks about a Harry Potter TV series remake, and it would have the opportunity to correct some of the biggest mistakes made by the original movies. The films are iconic and beloved, but several features of the Harry Potter books were altered or left out to fit the shorter format better—or to add a dramatic flair for the screen. This meant that the flavor of Harry’s story wasn’t quite the same from one to the other. However, if a TV series became a reality, it would have a chance to remedy some of the most significant issues.

Though a Harry Potter TV remake isn’t set in stone, Warner Bros is reportedly (via Bloomberg) working on a deal with HBO that would make each of J.K. Rowling’s iconic books into its own season for a series that would both stream and air on cable. This opens up a world of possibilities. Of course, there are a million ways that WB and HBO could get this wrong—and fans are likely to remain skeptical until they prove otherwise. Still, there is plenty of opportunity to improve the eight Harry Potter films, especially regarding some of their most criticized mistakes.

The Harry Potter Movies Shouldn’t Have Changed James & Lily Potter’s Ages

After binging the Harry Potter movies again and again, it’s easy to forget that the actors that played James and Lily Potter did not appropriately reflect the characters’ canon ages when they died. In the books, Harry’s parents were only 21 when Lord Voldemort murdered them. While their deaths were tragic one way or the other, there is something even more impactful about the young witch and wizard who were only just starting their lives but still dedicated themselves to the fight against the Dark Lord. Aging them up lessened the tragedy, something the TV series can fix.

The Harry Potter Movies Used Muggle Clothing Far Too Much

One of the charming things about the wizarding world is how witches and wizards with little exposure to the Muggle world had no idea how to appropriately wear their clothing. In the Harry Potter books, everyone in the magical community wore robes rather than more modern outfits—but this was retconned for the films. Sure, Harry and his friends were known to wear jeans and sweaters, but the three-piece suits seen in Harry Potter and Fantastic Beasts is something that has bothered fans for years. Hopefully, the TV series will represent a more accurate version of the wizarding world.

Harry’s Personality Was Overly Simplified In The Harry Potter Movies

Daniel Radcliffe was perfect for the titular role in Harry Potter, and the TV remake would have its work cut out for it trying to replace him. However, there are several ways that the character itself could be improved. Harry is sarcastic and quick-witted in the books, especially when it comes to adults like the Dursleys, Severus Snape, and Dolores Umbridge. However, his most comical lines were often given to Ron in the movies, which left Harry less relatable and interesting. Many of the movies simply saw Harry gaping at all the magic—but a more extended series could make him far more dynamic.

Dobby Should Have Been In More Of The Harry Potter Movies

Dobby the house-elf was one of the most wholesome characters in the Harry Potter series, which made his death in Harry Potter and the Deathly Hallows all the more devastating. However, this was significantly diminished in the movies since, instead of appearing in nearly every installment as he did in the books, Dobby was only seen in Chamber of Secrets before he was murdered in Deathly Hallows. To his fans, this felt like a terrible injustice. The movies likely cut his scenes to avoid the cost and time associated with animating him, but an HBO series might have the means to pull it off.

The Harry Potter Movies Neglected The Marauders’ Generation Entirely

For years, Harry Potter fans have requested a Marauders prequel movie since the films neglected their story. Now that a TV series is in talks, this seems unlikely to happen, but it might be okay if the remake gives the backstories of James Potter and his friends their day in the sun. This would need to include the truth about James, Sirius, and Pettigrew being Animagi—sometimes frustratingly left out of the Harry Potter movies—and more details about the friendship between Lily and Snape. This generation started Harry’s story, so it can’t be left out again.

The Harry Potter Movies Missed The Day To Day Hogwarts Experience

One of the most magical aspects of the Harry Potter series is Hogwarts. The castle is basically a physical representation of magic itself, and fans have long dreamed of attending for real. Of course, the movies’ beautiful set contributed to this, but they missed something special that the books often focused on—the casual day-to-day experience. On the page, the Golden Trio fudged through homework in the Gryffindor common room, had snowball fights in the courtyard, and joked around with Fred and George in the Great Hall. None of it was essential to the plot, but it was part of what made Hogwarts so wonderful.

The Harry Potter Movies Ruined Dueling And Apparition

The rules of magic in the Harry Potter series were often flexible, but they still followed a certain amount of logic. However, the Harry Potter movies threw this out the window for visual effects, leaving die-hard fans pulling their hair out. Phenomenons like Priori Incantatum, which only happened during a duel because of Harry and Voldemort’s brother’s wands, were used in nearly every wizarding battle in Harry Potter and Fantastic Beasts. What’s more, Apparition, which sees a wizard disappear and reappear somewhere else, was turned into flying around in a flurry of smoke. It just didn’t make sense

The Harry Potter Movies Cut Too Many Important Characters

One of the greatest difficulties book-to-screen adaptations often face is making room for all the characters. In the world of Harry Potter, Harry met many characters that varied in their importance to his story. Of course, some of these could be eliminated with no issue. However, their absence was notable in the case of individuals like Charlie Weasley, Peeves, and Winky the house-elf. This was disappointing to those who had loved these individuals’ roles in the books. However, a remake could restore these cut Harry Potter characters and make everyone happy.

The Horcrux Search Was Overly Simplified In The Harry Potter Movies

The Horcrux search was the climactic high point of the Harry Potter series. It started in Harry Potter and the Half-Blood Prince with a whole lot of background information and continued into Deathly Hallows when Harry took up the mantle after Dumbledore’s death. Even in the books, Voldemort’s Horcruxes were still shrouded in mystery. Even with his lessons with Dumbledore, Harry didn’t have much information to go off of. Still, Harry knew a lot more about the objects and the potential locations than in the movies (where he really only found them because of luck, not knowledge).

The Harry Potter Movies Minimized Neville Longbottom’s Character Arc

The Harry Potter movies left out a great deal about Professor Trelawney’s prophecy, which detailed how a boy born at the end of July would be Lord Voldemort’s undoing. This meant that the fact that this could have applied to Neville, as well as Harry, was also only explained in the books. This was frustrating since the insecure boy had one of the most dramatic character arcs of the series. Neville may not have become the Boy Who Lived, but a major point of the Harry Potter series is how this all came down to luck. By cutting these details, the Harry Potter movies missed out on a great story that the TV series can hopefully include.
