Other than some of the great choices that have already been listed here, I very much enjoyed Witch Hunter Robin, what I've seen of Scrapped Princess, of course anything Ghibli ( I know its been mentioned but seriously I love Ghibli), Vampire Hunter D (not the best animation maybe but really good stories), Vampire Princess Miyu, and Black Butler.
I could probably go on and on forever but figured it would be best to avoid repeat titles again and again. xD
