This would have been a much different experience if I had not read the books.
I liked most of the movie, even the small details they changed from the books, despite parts of it feeling rushed. There was much more they could have included, but it was already a pretty dense story. I think someone who had not read the book would have had a much harder time following everything that happened. The casting is very good, especially the voices of the daemons.
Then there's the ending where there is an entire scene missing. I was so shocked that they ended it in the airship! Lyra is heading towards her father's house, and many things happen in the book after she gets there. I suppose they'll put those scenes in the beginning of the second movie, but it would have been better to end it with her waking up and hearing the ominous warning from her father's butler.
