>>15653614rowling was bad at world building because she never sat down and bothered to define how anything in the world worked. magic or magic items don't have any general rules and do whatever the plot requires them to do, which makes them feel cheap
the best examples are how a bunch of teenagers created the marauder's map, but aside from that we never see other children making magic items, even though they should since that's what teens with magic would be doing constantly
or how she gave the most powerful wand to the villain, and then came up with the idea that wands can decide to cuck their owners arbitrarily because she needed a resolution
>You could also bring up the tired Tolkien/eagles issue and say “aha! Tolkien sucks at worldbuilding!” If you want to get that strict.that's a dumb meme. the eagles aren't magical taxis, they are their own race of demi gods with their own agency. they are also affiliated with eru and manwe, who had given up on the whole sauron/middle earth issue
the only reason gandalf got saved by their king is that they had personal baggage, and they came at the last battle as a final show of good faith for the end of the era
i also think tolkien gets some leeway because he was trying to create a mythological story told through specific framing (hobbit was written by bilbo, tlotr by frodo and the Silmarillion by elves), so it can be somewhat vague
harry potter stories don't do that, and heavily depend on the mechanics of how magic functions, which we are never told so it just looks cheap and like a chain of asspulls
also, the main harry-voldemort conflict is awfully written
