I'm guessing you haven't watched the making of documentaries for Jackson's LOTR trilogy? The trilogy was made with passion and great detail. There's nothing half assed about it. Even the costumes were embroidered inside even though it would never be seen on screen. Just to make it as authentic as possible.
I mean...you can dislike them all you want. But the movies in Jackson's LotR trilogy are objectively some of the best fantasy films ever made. There's nothing half-assed about them. They obviously went off the rails with the Hobbit, but that's a whole 'nother can of worms.

Game of Thrones is the single best and worst thing to happen to TV, because now everyone is gonna be like "We gonna make this the next Game of Thrones" on properties that are nothing like Game of Thrones.
When in fact J. R. R. Tolkien and George R. R. Martin's worlds are so different in aesthetic. .Its like trying to Game of Thrones up a Mario Bros. movie :P

Each to their own and all that but your reasoning is...odd. The Hobbit deviated waaay more from the source material than LotR. The deviations in LotR were hardly massive or tonally altering. And most deviations were leaving stuff out that they felt weren't essential, they had to fit it into a time limit. With some minor changes, swapping character roles (Eomer swapped for Theoden etc), the only really major one was giving Arwen much more screen time, or the ghost army showing up at Minas Tirith, which didn't really alter things in a significant way. Changes were made for the sake of adaptation.
The Hobbit however, dear god they added so much more in order to pad it out to 3 films, with some significant changes made to characters. It wasn't simply that they wanted to adapt it to screen, they wanted to pad it to 3 films. You are criticising LotR for doing something to a much less severe degree than The Hobbit trilogy, that said thing is bad, but its better if you do more of it, it doesn't make a whole lot of sense.
EDIT: Didn't notice how old the OP was.
They will 100% forsake a good story and characters for woke bullshit.
It does not need to be "realistic". Lord of the Rings is a very idealistic setting. The themes are very on the nose and that's the point. It's not supposed to be some deep, pondering piece about a reflection of our world. Also Lord of the Rings had one of the best relationships you can see on film and it worked without sex scenes - I'm of course talking about the relationship between Frodo and Sam. The relationship between Aragorn and Arwen is also beautiful.
It's completely ridiculous to me that every modern story needs to revolve at least partially around some half-baked romance because otherwise people will feel like something is missing.
Lotr has a lot of inbuilt clout and reputation but if they wanted to make another GoT they would have been better served picking up joe abercrombies first law series. I dont think we'll get another GoT, I think we'll get a series akin to the first trilogy in tone.

They obviously exist but they're not what LOTR is about. Also just because sexuality isn't on display doesn't mean a relationship is platonic. You can perfectly display relationships without sex scenes. If anything, sex scenes generally don't really add anything to characterization and are just there to attract the coomers.
Iirc the series will take place in the Second Age. There'll be plenty events to cover that will keep viewers entertained without requiring shoe-horned Game of Thrones style relationships, casual sex and the depiction thereof.
