I need some help finding some good anime. I am an absolute anime noob, but the few series I have watched were absolutely amazing and I want more of it. However, whenever I look for more I never get past the more mainstream manga and can't seem to find a good one.

Berserk and Attack on Titan were definitely the ones I liked the most and is kinda what I am looking for. Not sure if Afro Samurai counts as anime but that was pretty bad ass too. I tried Claymore too, because I heard it was similar to berserk, but only watched 1-2 episodes.

Basically I am looking for an anime that has epic battles and is a bit more serious/dark. Any advice?
