I can't fault him for any of his depth and character building and poetry and storytelling and descriptive environments it was all very thorough and for the right person wonderful. I think the movies did a giant justice to making his work accessible. There are a lot of people out there that can't manage to make their way through his poetry sections. And you can't not read the poetry sections because there's definitely content in there you need.
I came to this thread expecting to see this, and even with that expectation it makes me sad to see; to me the books are unarguably superior, to a large degree because Tolkien is such an excellent writer. I'd encourage anyone who's bounced off the books a time or two to go back to them and try reading them aloud, even quietly to yourself: even though it's prose, the text has meter and flow almost as strong as poetry. It's undeniably a slow read, but it's just such a beautiful one that the films, fun as they are, don't hold up.
It being better when read aloud actually nails what I dislike about it and, far more so, The Hobbit. They read like they were written to be told as tales around a fire, not to be read. So they don't work particularly well as books that you read quietly to yourself (imo, obviously).
