Well, it was a bit different from the original movies and I don't know about the books. Like I have said before I don't read much, never can keep my attention on a book for long most of the time.
Basicly it just gave the outline of there journey until the battle and all and then the ending. To me it could have been twice as long! lol But oh well it was still good.
The battle was pretty good. ( I tend to like fighting... I am not sure if that's a good or bad thing) But the witch was not as kreepy as in the first one. ... *thinks* lol I have only seen it once and don't remember a whole lot. sorry.
