It isn’t possible to overstate the impact this story has had on all kinds of media (books, films, video games, music etc) since it was first published in 1955. The world Tolkien writes about feels alive and full of history (in part because he spent years creating a complete overarching mythos and history of this world and the people in it (of which the Lord of the Rings is but a small part).
I own LotR and have read it. It basically defined the fantasy genre as we know it and has also inspired a lot not directly derived from it. But how it is written it didn’t click with me and reading it felt a bit of a chore and I have never felt revisiting the book.
