I am posting here in part just to get the Discussion Forum page to stop saying "Top reasons why you enjoyed....Legolas in spandex"
Actually, I loved how they tried to get the films realistic. The dirt under the findernails and scraggily hair and so on really struck me the first time I saw the FotR. Nice contrast between the high ideals and flavor of the book and the every day struggle of existance. Though Tolkien writes very descriptively it was wonderful to see, even if some parts were very different from how I imagined them.
