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)
But isn’t that part of making the reader explore and experience the world of magic, just like Harry is? There’s no narrator here who already knows everything, you’re experiencing the stories through the eyes of Harry, and only really know what he knows. In that context, it doesn’t really make sense to have these early clues. The reader can’t anticipate everything because Harry can’t either.
Magic in general is just a plot device that can do whatever the author needs it to do.
