It will be better than the movies which were glorified fanfiction. Hermione will hopefully not be the main focus and not take 90% of the dialog. Ron, Neville, and many many other characters will hopefully be better represented. Closer to who they are in the books. Sure the cast might not be 100% but neither was the movie's casting. Again Hermione being conventionally attractive instead of bucked toothed and frizzy haired.
