I thought that I would ask folks here for their least favorite book or recent major article about Tolkien, and why?
My answer would be Frodo's Quest: Living the Myth The Lord of the Rings, by Robert Ellwood. With a title like that I was sure that I would have enjoyed it. However, I found it a real disappointment. Ellwood's treatment seemed thoroughly allegorical. This itself seemed to me contrary to Tolkien's material. And, rather than an exploration of mythic roots in TLotR, it used elements of the story to set forth an introduction to theosophy. It came across as almost catechetical in style. The reader is frequently addressed in the second person.
I suppose that those who are of a theosophical bent might quite appreciate it -- and it certainly was an attractively produced volume. But I have to say that it didn't do much for me.
