I don't know, but given the sheer popularity of the movies, she seemed to enjoy them. She even got along well with the cast. Though her friendship with Emma Watson has been strained of late.
I remember in the production of Order of the Phoenix, given Kreacher's role was so minor, they were not going to include him in the film. But Rowling insisted for him to be included. This was before Deathly Hallows hit the shelves.
Good for her if she could accept the changes in the live adaptation version.
I read that Alan Moore, the writer and creator of Watchmen, has famously refused to watch any movie or television series adaptations of his work, including the 2009 Watchmen movie and the 2019 HBO series.

He believes that Watchmen was written specifically to utilize techniques unique to the comic book medium (such as panel layout and symmetry) that cannot be effectively translated to film or television.
