Sometimes it's beautiful and we fall in love with all that story. Even after a thousand pages we don't want to leave the world the writer has made for us, or the make-believe people who live there. You wouldn't leave after two thousand pages, if there were two thousand. The Rings trilogy of J.R.R.Tolkien is a perfect example of this. A thousand pages of hobbits hasn't been enough for three generations of post-World War II fantasy fans; even when you add in that clumsy, galumphing dirigible of an epilogue, The Silmarillion, it hasn't been enough. Hence Terry Brooks, Piers Anthony, Robert Jordan, the questing rabbits of Watership Down, and half a hundred others. The writers of these books are creating the hobbits they still love and pine for; they are trying to bring Frodo and Sam back from the Grey Havens because Tolkien is no longer around to do it for them.
