I was tipped of to this after a long online HP rant elsewhere.
The first few paragraphs showed me that Rowling, while not necessarily a good writer, is better than some other, and that the editing of HP, something i complained about, too, was solid, if not perfect.
Then i read most of the first three chapters, and it’s quite clear that the author has an axe to grind, something less like “the world building in the Harry Potter books is inconsistent and not thought through” but closer to “suspension of disbelief is silly and i want to show that magic can’t work in this world”. I’ll leave him at it without reading on.
