This isn't about being purist, it's about common sense.
Everything in this show is unwatchable, from characters behaviour, their actions, fights, roles, military strategy, how they represent their roles, the costumes, appearance... Nothing indicates that this is professor's Tolkiens work, this is how they want to represent it to us, adding their own beliefs.
It's someone else work that he created in specific way and studio's just need to move this into big screen, being loyal to the source material is unquestionable otherwise you disrespect originals creator's work and making fan fiction...
LOL I have a die hard Tolkien fan (who Ironically is very left wing politically so normally buys into all the woke stuff)
Him and his wife cancelled Amazon Prime 3 episodes in over the show.
I honestly don't know one Tolkien fan who likes this show (other then all the fake fans online that claim they fans but know zero about the material)
I get it too.
I've never been able to read Tolkien's writing style so my knowledge comes from being friends with die hard Tolkien fans as they discuss the works and of course the movies.
And even I know what we seeing in Rings of Power is NOT Tolkien's Middle Earth. Not even slightly.
My favorite fantasy book series is Wheel of Time by Robert Jordan and I had to shut off Amazons insulting and disgusting version of Wheel of Time at episode 7. It was sooo terrible.
Not even remotely like the books. Just some no name hack writer with zero fantasy writing credits to his own name destroying Jordan's work and replacing it with poorly written fan fiction as he craps on everything that made Wheel of time so great and beloved to readers.
The writing for Rings of Power and Wheel of Time have been the absolute shits and I flat out refuse to believe anyone involved in those projects "love the source material" in any way.
You do not intentionally destroy things you claim to love.
