I'm just not sure. Good catch, the fact that it isn't the same as the book. I get irritated when movies based on a book, or a series of books, don't do things LIKE they happened in the book. They can do it, though, because they say it is "based on the book "Blahdeblah, written by Blahdeblahdeblat". They don't claim its exactly like the book. We still know what they're doing..they're messing up a great story!
