One could say that's nothing, they continued even Jack Ryan etc. after their abysmal ratings, but it's very good to see that the viewership, which was minimal even after a huge marketing campaign (second season has undetectable marketing, Amazon knows it's a lost cause), is getting lower uninterruptedly with every episode.
Don't worry Mr Jordan, people care about your books, but they do not care about the 'adaptation'.
One silver lining is that I have seen people read LOTR due to being unhappy with Ring of Power as well as people getting the WOT books.
