As a HUGE fan of the books, and as someone who had been waiting for the film for about 4 years ever since I read the book, I was disappointed.
To be fair there were a few redeeming features to the film - Dakota Blue RicharRAB surpassed my expectations as a newcomer (expected a Harry-Potter-esque actress but much better than that), although she was a bit unconvincing/wooden at parts. Thought the graphics were stunning and liked the Magisterium dude (although his name was wrong (Fra Pavel? I mean, why??) and his role doesn't exist in the book). Nicole Kidman was perfect as Mrs Coulter, as was the guy who played Lee Scoresby and Hester. All the daemons were great.
Other than that.... a huge meh for me. The film was so disjointed and it was just one event after another. Some were so rushed (e.g. the battle of the bears - it was like "Yay Iorek, you're the new King! Now let's go to Bolvangar!"

). As for the ending, I nearly yelled at the screen when I saw it about to end. I'm sorry, but what IS the point of cutting out the ending?? The Amber Spyglass won't make sense without it, and they can't exactly plonk it into the next film either because half of it is about the disturbance Lord Asriel caused.
Didn't think much of Daniel Craig, I'm afraid. Never been a fan of him but he really did not have the authority, majesticness or the cruel power that Lord Asriel should have. When he was asking for money in the Retiring Room he didn't appear dominating but like a normal old man. And the unnecessarily Bond-esque sequence in the snow mountains added nothing at all. Serafina kept popping up at odd places to move the plot along several paces but added nothing. Ian McKellen's voice was distracting as Iorek as it is so familiar to us, plus he was too gentle/too un-rough for Iorek imo. The guy who played Iofur (NOT Ragnar... grrr) suited a bear's voice much better.
I didn't appreciate all the bad stuff being plonked with The Magisterium. I suppose it made things easier to understand but..... and I bet the Fra Pavel dude will take on Father Gomez' role in the 3rd film judging from the Beetle daemon.....!
The main problem of the film was time, ultimately. None of the characters had a chance to develop properly and it just feels like a giant trailer, with the highlights of the book being shown, but not actually telling a story.
The anti-religious stuff comes in mainly in The Amber Spyglass though. In Northern Lights it's hinted at but not made overly explicit. The first book does follow the basic skeleton of a typical adventure story (albeit much, much better than that imo), but the second and third books are not. If you can bear it I'd urge you to read on and see what you think of the entire trilogy, and whether you think it is boring and bland then. And when you watch the film and think it is better than the book.......... well!
