I am a major Tolkien superfanread all of the HoME stuff when I was a teenager, learned Elvish (hence using my Elf name for this forum), the whole deal. Have mixed feelings about JacksonLotR movies, though I think they are a bit of a triumph, hate the Jackson Hobvit "trilogy."
I have no binged Rings of Power through the Finale this week, and can render my informed judgement: this is excellent, every bit of the production is exquisite and the writers actually get Tolkien's themes on a fundamental level. The things they add fit in well and are very smart, and for the purposes of these artists telling their story, I don't really care about the creative licenses they took, because they work in themselves as part of a coherent narrative. Tolkien wrote multiple deeply contradictory versions of all his stories, so as long as the work is good, "canon" is irrelevant.
