The movie was live action and not all the actors were very good. Some even very long scenes were done word-for-word with the book, but others were completely left out, cut down, or combined with each other. The big problem there is that some of the items and ideas from the incomplete scenes came up in the word-for-word ones without the appropriate prologue.
The other big problem was that they told you what was going on and why things would cause other things, I guess because they assumed that the watchers aren't as smart as the readers.
It's three hours long and not bad, but not something you need to watch. I only bought it because Amazon had it for $5 and I was already getting something else and could get free shipping with this one, too.
