But once I saw the extended versions of the LotR I was very pleased. He really did fit in almost everything I missed. So I don't think you can really blame Peter Jackson, he does what he can for the fans. And I understand why he cut the battle in the Shire for example, it would make the Return of the King anti-climatic and drag on too long. But I did miss Saruman's death though... but he included that in the extended versions, perfect for me.
Overall I'm very happy with Peter Jackson's work. Having watched the Making Of discs, I realize that Peter Jackson really has a passion for getting it right because he loves Tolkien's work. And I think most of his cast and crew are like this as well, so I'm sure that even when they change things they do it to make it better. Or at least, that's their intention.
