A lot of people point out that it doesn’t make any sense that Harry and Ron didn’t like their schoolwork. Well I figured out why:
It’s because the magic system is just as boring in-universe as out of universe. It doesn’t make any sense in universe either. Harry and Ron realised Rowling’s magic system kinda stinks way before we did, because they spent all day learning it.
If Sanderson had been writing Harry Potter, then Harry and Ron would have liked learning magic as much as Hermione did (Also, Sanderson actually DID write a book about a super-school, it’s called Skyward, it’s good)
You know what? Rowling did actually follow Sanderson’s laws with one specific bit of magic. The time turner. The time turner has a very simple limitation: you cannot change the past. But, you can do things in the past that don’t change what you experienced the first time. We understand how the time turner works, and Rowling comes up with a clever way to make it work, which makes sense to us. That’s the second and first law! The time turner is well written!
And then she broke the third rule. She didn’t expand on it, she added something new in book 4 instead. So people asked “what about the time turner”, and in the next book she got mad and destroyed them all so she’d never be asked “what about the time turner” again.
Rowling wrote something really interesting that actually makes sense. And then decided she didn’t want it in her story anymore. Because Rowling doesn’t actually like writing interesting magic. And that’s why Harry and Ron aren’t very interested in magic. Rowling was never able to write a scene where a character actually geeks out about how magic works, because she doesn’t care how it works. She’s not interested.
