I frankly don't care of the changes as long as they make sense within the show and the story is good. Just like the LOTR movies, there was so much criticism about the changes by the fans, but I thought the movies were great despite the changes (and in some instances, because of the changes). Changes are necessary because a Movie or TV show can never go into the level of detail books can, plus the fact that they need to target a larger audience.
For Rings of Power, it looks like they are compressing 100s of years of the book story into a few years. I think that is a great idea, even if it leads to some serious inconsistencies with the books like maybe Gandalf coming in this age or Isildur being born before the rings are made. When I watch an adaptation, I like to judge it based on the story it is telling. As long as the show stays consistent with itself and tells a compelling story, I have no problems. So far I'm enjoying the show, largely due to the spectacular visuals as the story buildup has been quite slow in the first 3 episodes. Which is not a problem if the payoffs in the later episodes are worth it. The Episodes are getting gradually better, loved the scenes in Numenor & the Orc fight with the chains in the last episode. Intrigued to see where this goes.
I hope this stays better than what happened to Wheel of Time, one of favourite book series, where the writers made changes which ruined the world building within the show so much that a lot of it doesn't make sense.
