What puzzles me is that even Jackson's LOTR films got pored over by Tolkien fans who pointed out the flaws and rough spots. And they were kind for the most part.
Jackson's LotR films got a pass when the changes made sense. For example, having Arwen saving Frodo helped with two problems: that Arwen is a very opaque character in the book (when her importance should instead be front and center) and how Tolkien himself stumbled when he tried to explain why Glorfindel wasn't part of the Nine. So, Jackson solved a potential problem without betraying the lore (even the animated adaptation had Legolas meeting the hobbits instead of Glorfindel).
However Jackson was roasted every time he went astray: Faramir, Denethor, Eowyn (partially), surfing Legolas etc. And he had the time to cut Arwen from Helm's Deep battle (there are stills that still show Liv Tyler in the background) because
that one had the fans with the flamethrowers ready. In a way, studying when and why Jackson was grilled should have been a map to what not to do in TroP.
Cui bono? Who profits?
A scary theory is that Amazon/Jeff Bezos are playing the long game. Redo the Second Age (who cares if they lose money?) buy the rights to all-Tolkien and redo woke-LotR but now in canon - because the nu-canon is TRoP. The paradox, here, is that Amazon has the rights to the Hobbit and The Lord of the Rings right now - but they know that if they go against the Jackson's movies now they will be obliterated. Expect LotR in 2030 with a black gay hobbit, a trans hobbit, Frodo+Sam and Legolas+Gimli (one of the two PoC) and so on.
And if the madness of our times is, by 2030, a pale remembrance, Amazon can even try to do a proper adaptation - D&D Satanic Panic vs. 3E way.
