JKR's comments on the movie

[Annalisa Moretti]

This has been brought up, but I'd specifically like to apply what 
she's had to say to everyone's criticisms of the film.

I, too, was pretty upset about the deflated Shrieking Shack scenes, 
though in my case, that was the only objections to the film; I 
simply don't care very much about stupid little things such 
Hermione's shirt tails being untucked, or there only being one 
Quidditch scene, or Lupin having a mustache. That stuff is 
immaterial to my movie-watching experience.

Now, JKR, as we all know, is very blunt. I highly doubt she would 
give a good opinion of the movie just because Warner Brothers told 
her to. Therefore, my concerns over the Shrieking Shack scenes being 
cut -- which were only partially because of the effect it had on the 
plot of the movie, but instead focused mainly on whether this would 
prove disastrous for the plot of the overarching series -- are 
considerably calmed by the fact that she has shown no qualms over 
them. Personally, I would very much like to hear her say something 
specifically on those scenes. But I have some faith in her opinion.
