Wolf's Rain, even though the manga and anime had completely different story plots/endings.
Elfin Lied, most fucked up anime I've seen in a while.
Hellsing, favorite vampire anime.
Hokuto no Ken/Fist of the North Star, I'm happy they're decently dubbing the original series.
Deathnote, my friend lent me the live action movie I've yet to watch.
I used to like Inuyasha, until the ridiculous fillers and inappropriate death rattle they called an ending. However I heard the manga goes on after that point.
