All in all the book was quite a bit better than the movie, but on the other hand you can't really express broomstick riding in a book however much you try. The movie really captured and amplified the thrill of that sport.
For some obscure reason there was also a second DVD in the box, which seems to contain a Harry Potter game. As if the world wasn't packed and stacked with Harry Potter games already.
I still think someone should make a movie of the Chronicles of Thomas Covenant. Oh well.
