Yeah, I suspect that's why the Chronicles of Narnia only got the one vote and Harry Potter got few as well - HP becomes a YA series, but they start out oriented towards children. That's what makes Harry Potter hard to categorise (and so good) - the books grow with Harry, so that by the end I really consider the seventh book to be an adult book. Just without the sense of alienation that most 'adult' books seem to have these days.
