The castle literally falls apart at the end :) On a more serious note, the book is quite good too. The book doesn't describe the castle as a giant steampunk thing walking around in the hills. It's actually just a plain 4 sided stone building that hovers around a little over the ground, no legs. So in this regard the movie is better IMHO. But in the book there is another location the door opens to and the stuff we see in there changes the whole story. In the movie we spend some time trying to figure out what version of the characters, Howl especially, are the real version. The book turns this up further with the additional location. At the end the take away is quite different between book and movie. Both good in their own ways.
