Lol - but hey, Feanor is pretty cool, you have to admit. Without him and his sharp tongue and fiery temper it would have been one boring Arda.
And I remember that another character whom I strongly dislike (he's obscure in terms of amount of time devoted to him in the book but not significance) is Elrond, and I'm glad I'm not alone in this. All this talk about him being the wisest, and I really didn't see much evidence in support of this.
