Ok, so I knew going into this I was going to be a little disappointed -- if you're a fan of the books, how can you not be? Unless you've never seen a book made into a film before, I don't understand how you can't set yourself up for some degree of disappointment.
Having said that, I really enjoyed this movie. The visual effects were amazing, they did stay true to the general tone and emotion of the book. Yes, they changed some scenes, character experiences, etc - but it would have been impossible not to. I think they did a wonderful job and look forward to seeing it again in the theatre!
