I was taken a back at just how high the vitriol was on season 1
I was around the internet when the ramp-up to Jackson's films was happening and belonged to several forums of Tolkien fans. It was nuts - people were losing their minds over eye color or how large a dagger was supposed to be. I remember a moderator on one forum railing against every casting choice, leaked story choice, and pretty much everything else. He went and saw FOTR when it came out (why?) and wrote a review on the site. I'll never forget that he said he cried watching it because of how badly Jackson screwed up.
It's a million times worse now. When I saw they had cast Lenny Henry (the most accomplished actor in the whole damned cast), I thought "here we go...."
As an adaptation of Tolkien, I'd give the LOTR films a B+. I didn't like some of Jackson's changes (he butchered Denethor and was almost as bad with Gimli) and I thought he misread a few of Tolkien's themes, but I thought he did a better job than we had any right to expect. As films, they are monumental achievements.
I thought the Hobbit films were a mess and got progressively worse.
The Rings Of Power, I'm all in on. It's the least faithful adaptation we've had in terms of "facts", but I think they get the soul of the story (mostly) correct.
