check out Death Note. best anime ever its so addictive and youll thoroughly enjoy it from start to finish.
First of all, it all depends on what you like. Some of my favorites are Hunter x Hunter, Attack on Titan, Black Lagoon, Elfen Lied. If there aren't any to which you've seen before in this small list, give them a shot.
oh and Dororon isn't that bad either, it's so pervy, its hilarious
