Ok I seen the movie Friday and it was actually pretty good. There's a lot of stuff cut from the film which is fine it would have slowed things down. like Lyra nad Roger exploring the crypts of the college.
There are a few things changed and te one that really got under my skin was the the fact they changed Ifor's name to Ragnar. Now I like the the name Ragnar but because americans are dumb they felt people couldn't tell the difference between Iorek and Ifor.
There are some minor changes most of which I can point out but wont because I felt it didn't harm the film. Recently rereading the book I can also safely claim what I did like is a lot of direct quotes from the book are in the film.
Oh one other thing about the movie so no ones suprised. They left out the last 3 chapters of the book for the sake of picking up the sequal there. So all you know is Lord Azriel has been captured and Lyra is on her way to him. Beyond the irritating ending and the changing of the bears name I was quite pleased with the movie.
