The books are so much better than the movies, which are technically accurate but rather cold and mechanical run-throughs, even though sanctioned by Rowling. The strength of the books are not the stories as such, but the way that Rowling creates her world and the little details of Hogwarts and what it's like to go to magic school, things that evaporate in order to get the books in under the 3-hour movie-length ceiling.
And I couldn't see all the hype about "better than the first". This hue and cry was everywhere, throughout all the media, and it seemed like mind control to me. Say it enough and everybody agrees. I guess it had more action and that it was a little darker, with more tangible villains, but to me the children's performances had gotten ruined along the way, and the plot points were somehow all there but the movie was incomprehensible all the same. The dramatic thrust of what was going on was just not present.
I have hopes for the third film, which deals with the finest of the books, The Prisoner of Azkaban, but what they have done with the first two doesn't leave me optimistic. If nothing else, the sheer length ot the book is going to really require the film to be released in two parts.
Plus- what is being on a non-stop film shoot going to do to the lives of the poor children playing the main characters? It seems this could move from being the wish of a lifetime to the cause of mental breakdowns or worse very easily.
