It's unfortunate that so much of the book needed to be cut for time and the movie is still nearly 2 1/2 hours long. The rule of movie editing is when you must trim for time you remove the sub-plots. A lot of story and character development isn't there.
But what is there is a great visual treat. If the movie leaves you with questions just read the book or get the audio version on CD. It would have taken a minimum of another half hour to flesh the movie out and that simply wasn't going to be done by a studio whose primary target is a younger audience. (Note how no studio wants to release an animated film longer than 90 minutes for this reason.) Perhaps Alphonso Curon would have done a better job of cohesion but there really isn't much more that could have been done in the time and the script would have been essentially the same. This movie begs for an extended Lord of the Rings type DVD, another 30 to 60 minutes to give you what was left out for theatrical release.
See it and spend the bucks to see it on the big screen.
