I thought the special effects as well as the story line brought the conclusion of the story to a great end. Many suprises, twists and turns. Highly recommended (but watch part 1 before you go).
I think the movie was great - a little over the top with the animation at times, the horse drawn funeral cart had me jump from my seat once. It kept to the story well. The kids that were with me thought it was a little slow at times - one of them said "boring".
