TheHarry PotterTV show should stick close to the source material, but there are some stories I would love to see expanded in the series. By all accounts,Harry Potterhas established itself as one of the most engaging and popular franchises in modern history. From a series of books by a previously unknown author, to some of the most popular movies ever made and a fanbase that is immensely dedicated to the storybook world,Harry Potteris more than just a story.

And as efforts have been made to expand on that universe, with theWizarding World stretching into a spin-off franchise, various online resources, and more, there is a thirst from the fanbase to see and explore all that the narrative has to offer. The trouble is, within the pages of seven books, there is only so much information provided about various characters, and hints at things that could go much deeper. And the newHarry PotterTV show has the chance to expand on these detailswith its stretched out runtime over numerous seasons and episodes.

4Albus Dumbledore’s Connection To Grindelwald

Dumbledore’s Taboo Relationship Needs To Be Explored

While theFantastic Beastsfilms did make a considerable effort tounpack the relationship between Albus Dumbledore and his former lover, Grindelwald, the unfortunate recastings, and the other challenges facing the movies resulted in a complex and slow journey that delivered precious few answers about the future headmaster of Hogwarts.

With this big reveal now more public knowledge, the show could hint at and expand on this detail much earlier. It could see Snape make his promise to Lily, andunpack the complex feelings that he must be enduring throughout.
