That really underscores how bad the author’s “drama requires moral ambiguity” argument is. The Lord of the Rings: The Rings of Power did everything it could to inject moral ambiguity into a very unambiguous text—Galadriel is now an obsessive that disregards the cost of her vengeance, Halbrand presents as a possible Aragorn ancestor, Adar is just trying to redeem the Uruk, etc.—but all of it falls flat, none of the reveals land (“I am good!”), and the end result is simply narm. The casting of Arondir and Disa hardly makes a difference in the light of all these writing flaws.
