for me, Ragnarok the Animation was the one of worst animes I've seen, sadly ;/
anyways, my top 5 animes~
~ > Air TV [rewatched&rewatched&rewatched <3]
~ > Myself; yourself [great story for sure, even though anime has school life as a background]
~ > Claymore [ I love everything on this anime, but the ending, which was dissapointment ;/. They should make another season.]
~ > Nabari no Ou [again, one of better storylines, those who don't really like naruto, but still like ninjas, might enjoy it :P]
~ > Wolf's Rain [Well, just <3]
About others, which are worth watching, I'd say Hell Girl, Vampire Knight [Guilty], Shikabane Hime, Utawarerumono, Chobits, Fate/Stay Night, Soul Eater, When they cry [Higurashi no naku koro ni], Shakugan no Shana [atleast the first season] && Twelve Kingdoms
Oh, and I just finished watching 11 eyes and I can say its a good anime (:
