As a younger man I read the Lord of the Rings every year for 13 years.
It is one of my favourite novels of all time.
The films were brilliant, (the Hobbit less so, 3 films WTF)
I had listened to an old audio book of LOTR, but the narrators voice was horrible.
A bad narrator can ruin a good book.
Not the case here, Andy Serkis is great, especially the Gollum/Smeagal character.
It took me about two weeks of listening to get through it, well worth the effort. Listening to the book helps with the pronunciation of names.
The only things that could make this production better would be a full treatment like Neil Gaiman’s Sandman series on Audible.
The three Sandman audible books have multiple actors doing characters, excellent sound effects and music. In effect a movie sans moving pictures.
