I've seen the movie now, and I'm halfway through the first book (The movie was a BAD idea, cold movie theater and did I mention I'm even worse now? Ugh.). I must say I really enjoyed the movie, but I'm not generally picky with movies, and I'm just reading the book now, so it's not like I can notice the difference. Maybe I just liked James Bond as Lord Asriel, who knows?

My sister liked the movie as well, but she hasn't read the books either.
I'm having no trouble staying interested in the books, though. I can't stop reading!
