Ultimate Question: What is the best book/movie??

Best book is tied between 3 and 7. Best film is 4, I think (it's the one which changed details the least).

My favourite book... That's quite difficult to choose! I've always had a soft spot for Prisoner of Azkaban and Half Blood Prince, but I reread Order of the Phoenix recently and thought it was excellent. I think the best movie would have to be either Deathly Hallows part 1 or part 2.

My favorito book is either the Chamber of Secrets or Order of the Phoenix.
My favorito movie is definitely Goblet of Fire.

I still need to finish leitura the series but I would have say that my favorito book would probably be The Prisoner of Azkaban and movie is Deathly Hollows part 1.

My favourite book is Deathly Hallows, and with the filmes I prefer the ones after Prisoner of Azkaban, with no specific favourite.

the deathly hallows

I like Prisioner of Azkhaban and The Goblet of fogo (movies).

Well, I think they're all great...but I consider these two the best:
book - Deathly Hallows
movie - Prisoner of Azkaban
