Game of Thrones was pretty much G.R.R. Martin's fuck you to Tolkien. Tolkien had made a fantasy world filled with beauty, chastity, temperance, empathy, and a loving Creator who used the humblest members of His creation to save the world through their determination and sacrifice. G. R.R. Martin made a fantasy world that was basically "War of the Roses" filled with assholes and rape (and people getting raped in the asshole,) A world where common people lived at the mercy of corrupt aristocrats and impersonal natural forces. A world that stamps out idealism at every turn and if it has a Creator, He's probably the biggest asshole of all. It's is the polar opposite of LOTR and trying to twist Tolkien's work into a Grimdark Fantasy potboiler like GOT is akin to Cultural Vandalism. I hope whatever member(s) of the Tolkien estate that sold his work to Amazon enjoys their 30 pieces of silver, because once they die, they're going to have a very angry author coming after them in the next life.
It's also not written by Tolkien, so it's not canon anyway. So congratulations are in order for Amazon in making the first (to my knowledge, anyway) multi-million (billion?) dollar fanfic!IIRC they only sold it with several contractual clauses that limit what Amazon can do (can't race/gender swap canon characters, limiting them to a stretch of material timeline-wise which is a blank slate, and most importantly, NOTHING Amazon does with LOTR can fuck up the existing lore meaning they can't rewrite the trilogy and everything they do has to amount to jack shit in the overall narrative as far as "something that happened in a vacuum that no one remembers and had no impact on the world around it".
They also forced Amazon to take on a relative of Tolkein who's job was to police them and serve as a source material consultant and it was widely stated the guy was super serious in trying to tard wrangle Amazon and their hires to keep them from raping the source material and pointing out when they got dangerously close to voiding the above terms of the contract, which would nullify the entire endevour and cost them the right to do the show. IIRC he eventually ragequit because he realized that the creators hired by Amazon were actively trying their best to make it so they could just ignore him and having their own lawyers combing over the restrictions looking for any and all loopholes to get around said restrictions to allow them to rape the source material as opposed to creating glorified fan fiction that would be ignored and treated as such by normies.
If it's good, it'll be a nice study of that period in time of Middle-earth. If not, I'm just going to point and laugh at it.
