Rings of power was alright

No it isn't. It's terribly written. The speech of Sauron to Galadriel was something a five year old wrote. Galadriel just jumped into the middle of the ocean? Also she took a pyroclastic blast right to the face and doesn't even have a scratch? Whereas other characters are fully blinded.

And all the changes, which each on their own might be forgivable, but there where just so many that it all added up to something off-feeling and weird. It would be like shifting each note in a Mozart piece by a little in different directions, and then listening to the whole thing wouldn't be pleasant. This is another one of those things where they made changes for sake of change or to fit a particular story/reveal they wanted to write. Tolkien's works were already a masterpiece, what was the benefit in changing it? At best it adds absolutely nothing to the final product itself, and at worse just makes the whole legendarium muddied and disjointed.

For example, when the show took place Aman was not cut off from Middle-Earth yet. Specifically because it was cut off after Sauron poisoned the hearts of the Numenoreans and convinced them to attack the Valar and invade Aman. As a punishment Eru Illuvitar sunk Numenor into the sea and made all of Middle-Earth "round", so that sailing west would just bring them back around to the other side of Middle-Earth. So to get to Aman after that required sailing through a special path that only the Elves knew about, which is what we see in the show. But before the sinking of Numenor, anyone could sail west to Aman. And, IIRC, in the show we actually see a glimpse of Aman in the distance of one of the Numenorean ships. They regularly would see the shores of Aman in the far distance and wonder about it.

So if Aman was only reachable by the secret path, why could the Numenoreans see it from their ships? But in either case, this is a huge change in the lore and order of events. It might not matter to the casual viewer, but to fans of Tolkien (the people who are the hype-men for these kinds of stories, and generally the reason shows like this ultimately get green-lit) it doesn't make sense and breaks the story.
