Gandalf Vs. The Witch King

[Raynor]

Melian, a Maia, mothered the greatest of all the Eldar

But the only thing in which she apparently surpassed Fearnor was beauty; in all the other gifts of the elven race, Feanor excels ("mightiest in skill of word and of hand, more learned than his brothers; his spirit burned as a flame"; "he became of all the Noldor, then or after, the most subtle in mind and the most skilled in hand").

Others can only see LotR as a microscope over the latter part of the Third Age of Tolkien's Middle-earth, a product only of what came before it and not of any conscious desire of the author to create moral lessons.

So, Tolkien's opinions on religious and moral truths that appear in his work have no weight for you?

[The Saucepan Man]

Obloquy, it is quite clear from Tolkien's Letters that he perceived LotR, the book, to be, partly at least, concerned with the "ennoblement of the humble", the weak prevailing over the mighty. I don't have the Letters to hand, but there are a number of quotes to that effect. Whether he intended this from the outset is less clear, I believe, but it was certainly part of his perception of his own work. And, regardless of whether you share that opinion, it is clearly open on the material for readers to perceive it in that way.

Quite what this has to do with the portrayal of the confrontation between Gandalf and the Witch-King in the film, though, I have no idea.
