BTW, just read a book called "Harry Potter and The Bible"; I mention it only because there is a chapter in there re: LOTR.......basically praising it & drawing distinctions between Tolkien's writings and the H.P. series, the most obvious being the clear delination between good & evil that exists in Tolkiens' work, but is somewhat blurred in Rowling's. A good read.
I liked the Harry Potter books pretty well, read them with my daughter and found them charming. I didn't see the delineation as blurred at all in them, just see the books as generally more lightweight in every way than LOTR. In spite of all the (I think unwarrented) controversy about them, I see them as a good influence on kids, unlike, say, most TV or Hollywood stuff.
But I'm glad that LOTR is our book.
