though I hear the criticism that she essentially just rewrote Star Wars in a different setting quite often
That's nonsense though.
I've read all the HP books and seen all the films. No comparison really.
Dune and Star Wars are closer (and not really the same, though you COULD argue that the first SW film copied Dune book a little)
I thought he was very good at 'ripping off' most of the fantasy genre
The first two especially. He does a good take off of the Dragon Riders of Pern. In the later books it's more distinctively his only world. The early books give a Mediaeval 14th C & 15th C impression, but later it seem a much more 18th C and 19th C style of world.
Very famous.

Ballet Shoes (there are a bunch of famous "Shoe" books)
Lorna Hill "Sadler's Wells" series (she has other series). I have 1 to 11, but missing 5
Jean Estoril "Drina" Series (I'm missing the last two, 10th & 11th). Also the "Ballet Family" books.

Lucy Jane at the Ballet
I read them all and loads of English Boarding school stories (Angela Brazil, P.G. Wodehouse, Elinor Brent-dyer, Evelyn Sharp, L.T. Meade, Charlotte Bronte (Professor and Villette), Enid Blyton, Anne Digby, Antonia Forest and a bunch of others 19thC and early 20thC)
I read Tom Brown's Schooldays and Jane Eyre years ago.
(Have a look on Gutenberg, though no Enid Blyton, Anne Digby, Antonia Forest, or Chalet School (Elinor Brent-dyer), Lorna Hill, Noel Streatfeild, Jean Estoril I think)
Yes I know I'm 45 to 50 years too old for most of those books. But I suspect I enjoy them now better than as a kid (I only had read a couple of the Enid Blyton "Mallory Towers" then, and only last year discovered she was simply copying a formula started in 19th C. Though the earliest related books in the Genre are late 18th C!)
Very important research for my Special College. The students HAVE to go. No exit till Journeyman. Not even weekends. My SF stories in fact only have "Magic" so as to justify the existence of the Special College. Also why the Earth Woman leaves with the Aliens.
