Perhaps a very novice reader or viewer who has a very loose understanding of what fanfiction is might make such a wrong assumption. But if you analyze the two series in depth, you'll find that Harry Potter has its own rich tapestry of magic, family, and friendship, and Superman has his own lore of being an alien and a superhero. There is no aspect of Harry Potter that is borrowed or based on Superman in a way that would make it a fanfiction.
The details. It has a lot of specific details about the equipment, the environment, and the daily life of soldiers in Vietnam War, which makes it seem real.
The dialogues. Since there's no way to know exactly what was said in private conversations within the royal family, the show invents a lot of the dialogue, which gives it a fictional feel.
The detailed descriptions of Pi's survival skills and the challenges of being at sea make it seem real. Also, the way he deals with the tiger on the lifeboat is so vividly described that it gives an air of authenticity.
The vivid descriptions. The way Elizabeth Gilbert writes makes it seem almost like a fictional story. She has a very engaging writing style that can make you forget it's based on real events.
Well, the fact that 'Uncle Tom's Cabin' seems like non - fiction is due to several factors. Firstly, the emotions and experiences of the characters are very relatable. The pain, the hope, and the struggle of the slaves in the book mirror what real slaves must have felt. Secondly, the author's accurate portrayal of the social and economic aspects of slavery. For example, the role of slave owners, the trading of slaves, and the impact on families. These details make it feel like a true account, yet it remains a fictional work designed to expose the evils of slavery.
Maybe it's just a huge misunderstanding. Some people might not be very familiar with the true nature of both Harry Potter and the concept of Draken fanfiction. They could be misinterpreting some similarities in very broad terms, like both being in the realm of fantasy, but that's a very weak connection.
The backstories. The Marauders' backstories are so rich and intertwined with Harry's world. For example, Remus Lupin being a werewolf and his relationship with the other Marauders. Also, the fact that Harry inherits the Marauders' Map. All these things create a connection that gives it a fanfiction - like feel.
The setting. Hogwarts is a school for wizards, which is similar to the types of institutions often found in mage fanfiction. It's a place where young magic - users learn and develop their skills. Also, the existence of a hidden magical world parallel to the Muggle world is a common trope in mage - related fictional works.
The detailed descriptions of Pi's survival at sea make it seem real. His struggle with finding food, water, and shelter on the lifeboat gives it an air of authenticity.
There are several elements that make Harry Potter seem like Sherlock Holmes fanfiction. Firstly, the idea of a hero on a journey to uncover the truth. Harry's journey to defeat Voldemort involves unravelling many mysteries. Secondly, the use of clues and evidence. In Harry Potter, there are often small details that Harry and his friends pick up on to progress in their mission, similar to how Holmes uses clues to solve cases. And finally, the sense of a larger world with many hidden aspects waiting to be discovered, whether it's the wizarding world or the seedy underbelly of London in Sherlock Holmes stories.
