[Sauron the White]

I would agree that JRRT knew his work better than anyone else. His work was writing about Middle-earth. But then I read this from Mr. Hicklin

And if Tolkien himself couldn't pull it off, how could anyone else?

Are we saying that JRRT was beyond the powers of every other individual who lived in that regard? In the past I have criticized some here who seem to take an almost reverential attitutde or religious fervor regarding JRRT - and now this seems to partially support that suspicion.

Is it possible that someone could improve upon JRRT works? Yes. He was a man - a human being. He was not one of his gods.
