If you haven't finished it, then how do you know about all those elements you just mentioned??
I didn't cry at RotK (I teared up, but didn't cry). I didn't cry at the books. (The Passion of the Christ made me cry, but that's another story) But every time I read the book, the end of RotK, I put down the book and seriously, I walk away with a heavy heart. What else is there to say? It's just sad! But if you read the appendices about Aragorn's death...it's like MAN, what a creep Tolkien was to tell us how it all ends! It's kind of like Bilbo. We all want to have his ending. "And they lived happily ever after to the end of their days."
Stilll, you really have to finish it.
You may not remain on this board unless you do, we shall all retrieve our officially licensed Sting reproductions and drive you away.
Don't read the story of Aragorn and Arwen in the appendix, though, if you fear knowing the end. It's just not fair.
