It’s one thing to know that the elves freely used Sauron’s Rings of Power when they didn’t know who created them, but after a whole scene about how they’re the tools of the enemy, watching the elves put the rings on anyway felt ridiculous, a sudden introduction of ends justifying means that was simply foreign to Tolkien’s world by clear design.

My brother in Ilúvatar, the entire reason they give Frodo the One Ring in the first place is they held a whole summit to decide if they try to use it or destroy it and the only reason they don't use it is Elrond tells them it won't work because it's Sauron's. And even then Gloin has this whole thing where they try to figure out if they can find the rest of the rings and they go over them one by one to see if there are any available to use.

And then Frodo refuses to destroy the ring anyway and they only save the world because Gollum kept enough teeth in working order.

Hell, Elrond explicitly says nothing is black and white in the process of explaining this to everybody:

And that is another reason why the Ring should be destroyed: as long as it is in the world it will be a danger even to the Wise. For nothing is evil in the beginning. Even Sauron was not so. I fear to take the Ring to hide it. I will not take the Ring to wield it.’

FWIW, I thought the first season of RoP was... fine? It's a weird adaptation to attempt, but in the vast, sad landscape of derivative LotR work it's far from the worst. I'd watch it over the Hobbit movies any day, honestly. I haven't started the second season, but I will definitely get around to it at some point, and it's entirely possible I will feel it misses the moral core of Tolkien's work... but I'd certainly not express it in the terms presented in this article.
