I'm currently going though the books and from what I can tell, Harry especially takes issues with some teachers. He hates history and doesn't understand divination but he's fine with charms, defense against the dark arts and even potions once Snape no longer teaches it.

It's just that during the lessons she describes, they usually have stuff like Quidditch or Voldemort stuff going on so they don't really pay attention. They also don't like doing homework so they let Hermione do it for them. And they still did pretty well on the OWLs so all in all, I think they were fine with class but by and large, she just doesn't really write about classes that went their regular course.

I think magic went through a dark age in the HP universe, where all the words that were imbued with power were done so aeons ago, and then that knowledge of how they came to be was lost, with only a few handful having been rediscovered in the modern era.

Exceptions like "Point me" might just be english analogs of existing spells, rather than new inventions.

There’s was almost no magic!

Who sanderson

Or they're just lazy? 🤔

I like how Patrick Rothfuss wrote about "magic" in his Kingkiller Chronicle... I think it was explicitly called something else (been years since I read the books), but it was pretty fucking cool.

It was like daoist in nature almost, if I remember correctly.
