It really doesn't, especially when it's revealed (Very early on) that magic is literally just saying the right words and waving your wand...

But how can wizards be stronger than other wizards if this is the case? Which the book states that some are....

And there are Wizards said to create new spells all the time as part of their jobs... but... how the fuck does that work if the words and wand movement are all that's important? In most settings where it's via some magic essence combined with force of will, it makes sense how you could conjure up spells... but here it's like somehow being able to create a new console command for a software you can't update or modify...

Plus the scale of what magic can do changes depending on the scene...

Hagrid, a high school dropout with a broken wand concealed inside an umbrella, can effortlessly turn Dudley into a pigboi..... but learning how to take on just one animal shape is super difficult and only a select few called Animgai can do it... Sure....

Oh and an IMPOSTER Mad-Eye Moody casually turning Draco into a full-on ferret despite Animagis being this rare and overly difficult to learn thing is also bullshit.. (neither Moody nor the imposter were an Animagi)

And Hogwarts Legacy just has Animagi as a common enemy type despite them being so rare, but... hey there I can forgive it because without them we wouldn't have good enemy variety (Why are all the creatures in the forbidden forest spiders!??!?!)

Like, what are the rules? Because if Rowling doesn't care, why should I?
