truepenny asked what people's favorite parts of The Lord of the Rings were, as a personality litmus test. Many answers were provided, and what I found fascinating was the incredible variety—from "Book I of The Two Towers" (me) down to specific lines, and covering practically every part of the books. (No, I don't know what my choice says about me, except that I was eight.)
Tolkien said, in the Foreword to the Second Edition, that "the passages or chapters that are to some a blemish are all by others specially approved." Whenever I see that line, a specific "blemish" immediately jumps to mind— it's that dratted woman Ioreth nattering on during the coronation. Looking at it again now, it's only the two instances, but it seems like so much more.
(No-one's listed that as their favorite yet, at least.)
So, what's your least favorite part of The Lord of the Rings?
