While we don't HAVE to interact with him to know these things....its certainly enjoyable to see it in action. Show don't tell as they say.
I wish that the "Show don't tell" mantra had been extended further.
The reason that I brought up the Miltonic Satan, is that I think that it is very
hard to distill a character with real, evil gravitas into an - at least semi-relatable - protagonist without diminishing the mythic status. It is an ambitious project.
Milton can execute it because of his perspective: an unconventional personal theology, a deeply poetic and insightful mind, and an encyclopedic knowledge of classical, Judeo-Christian and Gnostic literature; as well as his deeply-held anti-monarchist and disestablishment beliefs. The resulting character demonstrates great pathos but his
evil is never really in question. Satan does not emote, or succumb to sentimentality.
I guess I'm saying if I were to try to put Sauron on the screen, and elicit a sympathetic response from the audience, Milton's Satan might be a port of call for inspiration. As might
American Psycho, for that matter.
When we examine the various iterations of Sauron in Tolkien's writings, we have:
- The fallen angelic spirit at the beginning of time
- The steadfast lieutenant who maintains Melkor's dominion during his captivity
- The cruel, shapeshifting lord of werewolves who beguiles and deceives with illusions
- The deceiver of the Elves and the forger of the rings
- The warlord who attempts to subdue Middle-Earth
- The corruptor who instigates Numenor's destruction
- A spirit, temporarily banished, who strives to reform
- A necromancer who corrupts the greenwood
- The final iteration, in LotR, who combines many of the previous elements to one degree or another
But at no stage is he personalized, with relatable characteristics; he is always "othered," because of his mythic status - literally,
The Enemy. His "role" is always archetypal; as are, arguably, most of Tolkien's other characters.
To invert that, and cast him in the role of protagonist, without jeopardizing the Sauron-
gestalt is a very ambitious undertaking.
I reject the notion that "modern audiences" require a morally grey character; I think better of them than that.
