There are some things I absolutely love about his LOTR movies, especially The Fellowship of the Ring, but I recently re-read the books and, in addition to all of the things you mentioned, I was reminded how awful it was for Frodo to tell Sam to leave. Especially compared to some of the amazing dialogue between them on the path/stairs to Cirith Ungol. I also can't stand Faramir's character in the movie compared to the books.

I enjoyed the first season of Rings of Power, though Galadriel's character was annoying in some ways. Since there is so much less source material for Rings of Power, I'm less frustrated by the creative license they have used liberally.
