I want them to follow the book as strictly as possible. I don't want them to try to add diversity or try to add any headcanons or things because when writers try to change things, it enrages people who liked the books. (True bookworms get it)

I want them to make it as accurate as possible because PoA-DH2 were not very accurate to the books.
