Paradoxical

Ever notice that anytime there's a credible villain, he usually gets some recognition in the titles? Three of the six Star Wars subtitles refer to the bad guys. The Lord of the Rings is named entirely after its villain. The Wrath of Khan isn't called Kirk Whines a Lot, and Wrath of the Lich King sure as hell isn't called A Bunch of Noobs Running Around Getting Their Asses Handed To Them. Why, then, out of seven Harry Potter titles, does not even one so much as mention He-Who-Isn't-Cool-Enough-To-Be-Named?
