That’s poetic but it’s a poor way to characterize the First Age described by Tolkien in The Silmarillion, in which redemption comes literally in the form of a Deus Ex Machina.

It’s also not a great way to characterize the Second Age, since both a portion of the good and a vital portion of the evil sides in the conflict survive and both are very greatly diminished, but I don’t think the writings about the Second Age were really central to that work. That’s why the show (which I haven’t seen yet) seemed like perhaps not a terrible idea to me. There’s not much legacy there to tarnish.
