I like him, but for me, it’s Stephen King, a lot of his stories he goes off on a twenty page non-relevant rant.
Though, the ones where he keeps that to a minimum, are great.
Then there’s Mr. Marketer James Patterson who markets out his name to other authors making it look like he wrote the book when it was obviously someone else.
So, Tolkien was a highly talented linguist with a focus in Germanic languages and culture. He created an entire language and world based on those languages. He also wrote more than just one book. Your ignorance of Tolkien could fill up an entire book, though.
