Naruto, Elfen Lied, Devil May Cry, and Melancholy of Haruhi Suzumiya are some great animes. Especially Elfen Lied.
the best animes i've ever watched would have to be... Tengen Toppa Gurren Lagann (wowow, i love this one. everyone episode is intense and full of action) The Melancholy of Haruhi Suzumiya (2nd season is confirmed yay!) Cowboy Bebop (a classic) Samurai Champloo (Beautifully animated and one of my favs ever!) and a few people like this one and a few people dont, but i personally like it: FLCL
claymore has gone anime? last i checked they were still in manga...then again that was a while ago but it looked cool
I loved FLCL.. I wish it had more episodes. I was still at the point of not knowing it was anime, and I had just started watching Adult Swim a year before they started showing it on there. Um, being around 13 at the time; it was funny, because my mom didn't want me to watch that show.
I finally got around to watching both Death Note and The Melancholy of Haruhi Suzumiya. I'm only on episode 22 of Death note, and its really addictive and makes you think a lot, which is good. I'm kinda mad that I watched all the way up to Bleach 143, and they're on 150.
Trying to watch Ergo Proxy, but I can't find any fast torrents(fastest I've found takes 24 hrs ). Fate Stay Night was awesome though imo.
Especially Gurren Lagann... I don't want to stretch the page, but this is a hilarious 4chan screeny http://img529.imageshack.us/img529/4955/1196482797618mm1.png
I never watched too much anime, but a few that really stood out to me were... Berserk RahXephon Death Note Dragon Ball Z (Not anymore, but as a kid I absolutely LOVED this series)
