I'm about to the point I could care less about these films. Now let it be said I absolutely love Tolkien's works. But you take out Bombadil, you take out Radagast, and now the Scouring is gone? Why bother calling it LOTR? Why not just call it Fantasy Movie based in the Middle Ages Part II. This sickens me!!
Tolkien's story was rich... full of a lot of texture. It can't all be done billbears! I am not so rigid as to not allow another fan (which Jackson is) to retell what he thinks the important parts are - his favorite parts. Any one of us might have different favorite parts of the same story. - I think so far the story has been told with great care.
The movies are a summary - a retelling of the story. Not meant to replace the book, but to illustrate the book and give another interpretation. If you look at it like that, perhaps you can be happier than if you expect a word-for-word duplicate of the book.
