Hot take, the battles in the book aren't great because Tolkien doesn't want to glorify violence. Half of the fights are like two pages in the books before the point of view character passes out. After realizing that I was kind of disappointed in how "campy early 2000s action movie" the battles in the films are.

There certainly are things I liked better in the books, I remember that much. But when judging entirety of books vs entirety of movies movies were better in my opinion.

(I'm only talking LotR itself ofc)
