Isn't that exactly what is getting Tolkien devotees twisted in knots?
I can empathize both with people who want to see something new in a Middle-earth setting and those who don't want to see anything incongruous. It depends on how happy you are with the original. For example, traditional Westerns bore me to tears, and I only really like Westerns that make a drastic break with tradition, like Cowboys & Aliens (2011).
I love the stars, and that was what attracted me.
However, I found myself not liking the characters too much.
I don't 100% agree on your take that Tolkein's stories were outright chauvanistic, but I do agree that the tone of the show is different to the books and the movies to its detriment. Rings of Power does not feel like an Epic in the genre sense, like Beowulf, which was a genre and style that Tolkein knew very well. The show feels far too...casual, the dialogue too sitcom-y at times (the dwarf scenes are brutal), and the world too clean and empty. When there are "epic" scenes, they end up feeling more like Disney or power rangers stuff (akin to Legolas riding the shield down the steps, I must admit).
While the effects are, at times, fairly incredible,I also think the writing has been an obvious weakness. The show is just kind of floating along in permanent exposition land. Only when a certain "dark land" is finally created does it actually start to have any stakes at all, but that is 5/6s of the way through the season already. By focusing on 5 distinct storylines for most of the show they keep everything in the shallows.
You can't write Tolkien elves like that. At this point in the story Galadriel is like 3000 years old yet her dialog is that of an inexperienced teenager when she has already seen everything (or knows someone who has) there is to see in the whole world.
Then there is the tone. The harfoot sections are the most unwatchable with an almost Dinsey vibe. The Numenoreas acting feels like the cringey dialog right before they start singing in a musical.
I'm curious, because aside from the disregarding the lore, attacks on fans, etc., in the end, the show was just boring. Like seriously falling asleep boring.
Make all the women act like toxic men, and make all the men act effeminate.
It goes back to the old line: "Being powerful is like being a woman. If you have to tell someone you are, you aren't." Galadrial in LOTR was an insanely powerful, to the point it was frightening. But she acted like a woman, not an arrogant man.
The writers are so clueless as to how to make a woman be a powerful character, the only way they can figure out how to do it is turn her into Captain Marvel / Rey / Mary Sue.
The archetype itself isn't new. If anything, women were overrepresented in that archetype as side characters for decades. Changing the character's role just doesn't magically solve the need for the archetype to interplay with others in a less brash way.
The finale worked for me, though, and retrospectively made the overall narrative flow work for me as well, so that makes it easier to dismiss the self-indulgent deadwood as ultimately I felt the core story was solid and well-told.
On Tolkien's chauvinism, one review I read noted that Tolkien doesn't come across as especially sexist -- as in, he's not anti-woman -- so much as he just kind of forgets about women. Which, granted, is still a form of sexism, but one that leaves a gap that can be filled rather than a hostile rejection that would be difficult to overcome. So like you, I've been enjoying the Galadriel character, and really the general increased peopling of this world overall, and don't feel it necessarily contradicts Tolkien's writings so much as fills them in.
That's just your toxic masculinity creeping through.
I kid, I kid. The biggest lesson here is calling out these types of absurdities gets you "labeled". This is the real issue.
The stories were basically written from whole cloth, based on fairly short mentions, in the four "later" books. From what I understand, they weren't even allowed to use Tolkien's notes.
I haven't encountered anything that has made me think this was a different "universe," but the general "feel" of the show is vastly different from Tolkien's writing.
For one thing, ol' J. R. R. was more than a little chauvinistic. Women didn't really play much of a part, in his writings, and when they did, they were fairly peripheral, or "objectified" (not necessarily in a sexual manner, but they were obvious stand-ins for some ideal).
I've been enjoying seeing Galadriel as an arrogant ass-kicker, but am a bit disappointed in a flower-sniffing Elrond.
