I think it goes further than that, and I can fully understand why Liliana made that comment. Tolkien is one of those authors who can be read at different ages, to different effect. I first read The Hobbit when I was 12, and was captivated. Re-reading it at 17, I found depths I hadn't seen before. I read it again in my early 30s and related to it even more, based on my increased knowledge and experience of life.Because the style in which it is written leaves no doubt that it is written for children.
