Harry Potter has no true self to discover. From the first to the last page of this pile of rags he is a wizarding Mary Sue with near-infinite privilege and the personality of an oyster. The story opens with “yer a wizard” in the first 50 pages and that’s the end of his character arc. From then on he’s a mere vessel for the reader to experience the world and the author to move the plot along.
… As a matter of fact, what even is the biggest character arc in that story? I don’t remember much, but Neville and Hermione have a glowup and Harry’s uncle dies or something? And the weasleys open a shop? I certainly don’t recall anything that lends credence to the idea that Rowling even believes that either individual people or societies are capable of profound change. The story begins and ends basically in the exact same place except the characters are 10ish years older.













I am not saying it did not sell. That’s the one thing it did really well. But it’s hardly a hot take to say success is not a measure of quality. Plenty of mainstream slop out there. HP is slop. It’s not offensively bad, but it’s certainly not good.
Over 6+ books it’s really sub-par writing to have a character who does not really grow because they already did not have any internal flaws or conflicts. The upside is that it’s really hard to hate a blank slate MC and you don’t risk writing yourself into a corner. I’m sure this is no small part of why there is so much HP fanfic specifically – it’s hard to write those characters badly as they lack so much depth!
Tons of things did the HP formula better, with well developed characters, good worldbuilding, good plot, good themes, yada yada. e.g. The Magicians (only saw the show) or Misfits&Magic. And in all of those the protags face strong personal hardships and are drastically different people by the end. Yeah, it’s hard, but that’s what storytellers do.
