So I completely understand that movies are not books. They are a different media all together and you get different things from them. I understand that when making a movie adaptation, it can be really difficult to please everyone because it's hard to squeeze all that content into a watchable length of time and not bore the crap out of anyone.
That said, I do think there are ways to do it. For example, you might choose to omit things from a movie that were part of the book if they are not central to the storyline. Or combine certain elements, or... whatever. I don't think they tried to do any of that in this movie. I think they just wanted to cram every scrap of the book into the movie that they just managed to give a summary of the book. I felt like the scenes were really rushed, barely able to get into a scene before being whisked off to the next event. Nicole Kidman was not very believable as Mrs Coulter. You felt there was something off with her right from the beginning when they should have made you like her, as Lyra does, at first.
All in all, I felt it was just a rushed summary of the book. I would have preferred to miss out on some key scenes and seen some deeper development of the more important points, or just a longer movie. The graphics were nice and the movie itself was pretty to watch, but overall a poor adaptation of the book. I found it at least entertaining, although if I hadn't read the book I probably would have been confused at parts. The book was excellent so I hope the movie doesn't discourage others from reading it.
