[Lord of Angmar]

I don't think so because, if Frodo had not shown him mercy at Henneth Annun, Gollum would not have been present at Sammath Naur and the Ring would not have been destroyed. And there is a certain tragedy in that.(The Saucepan Man)

I daresay there is.

For my personal enjoyment, I would have liked to have seen the scene the way it was described in the books. Heck, I would have liked every seen the way it was described in the books. But, as always, you make a good argument Saucepan, and I can see what Jackson was thinking in changing the structure, particularly in regards to audience understanding and appeal. While I was not a big fan of the lembas scene, I would not say I was tremendously discouraged by it.

For me, it seems more likely that Gollum would have accompanied them to Mount Doom and then, driven by the irresistable call of the Ring, attacked Frodo for it.(Saucepan Man)

Are you telling me you disagree with something Tolkien stated in letters? That is a pretty powerful canonball to fire into the conversation. I do agree, though-- I can't see anyone voluntarily destroying the Ring, let alone Gollum, however bound he was to his Master. The Ring's sway over Smeagol would reach its zenith at the Sammath Naur.
