LW, one of my favorite parts of the trilogy is the meeting with Sauraman and worm tongue on the road home and the defeat of him and the humans in the Shire afterwards. It was a microcosm of the entire tale on a hobbit size. It can also be viewed (and I do) as a early defeat of the return of evil. If roots can not be sunk, then evil can not be established.
It saddens me that this part was removed but gladdens my heart that the seaward journey of those who live forever was was included, and had to be accounted for - otherwise, how does one explain the reign of man
