One of the things I hate in fanfiction is when the author changes the personality of a beloved character for no good reason. It can be really jarring. And the over - use of angst for the sake of it. Not every story needs to be super dark and depressing all the time. Also, when the dialogue is stilted and unnatural, it takes away from the overall enjoyment of the fanfiction. Fanfiction should flow well, like a conversation between friends, but when the dialogue is off, it's a big turn - off.
Well, in some cases, the quality of fanfiction varies greatly. There might be a lot of poorly written fanfictions out there that use the Harry Potter name just for popularity. These might have bad grammar, inconsistent characterizations, and illogical plots, which can make the whole idea of fanfiction based on Harry Potter seem annoying.
The large and detailed cast of characters. There are so many characters in Harry Potter with their own personalities, backstories, and relationships. Fanfiction writers may struggle to keep all these elements in mind and might find it annoying when trying to incorporate them into their own stories without making mistakes or contradictions.
If they're starting to get on your nerves, it's a clear sign that you should stop. There's no point in subjecting yourself to something that annoys you. Maybe his stories have changed in content or frequency, but whatever the reason, your annoyance is a good enough reason to quit watching.
Well, perhaps Hermione starts debating with Snape about magical theories during class. She might bring up new research or different interpretations that go against what Snape has been teaching for years. Like, when Snape is talking about the properties of a certain magical plant, Hermione could say 'But Professor, I've read in an old wizarding journal that the plant has additional properties that we're not considering.' This would surely annoy Snape as he's not used to being challenged in such a way.
Hermione's intelligence means she can quickly spot flaws in Snape's statements. So, she can correct him, which annoys him. For example, if Snape makes a small error in a potion ingredient amount, Hermione will point it out right away.
Hey, I recommend the novel, Why Are You So Bad, to you. The female protagonist in the story thought that the male protagonist liked women with heavy makeup, so she deliberately put on heavy makeup for herself, but it caused the male protagonist to hate her. There were still many exciting plots in the story. I hope you like this fairy's recommendation. Muah ~😗
