Its a great show, has good character development and decent animation. The anime is "revengers" who take revenge for those you themselves can't , now you may think what if the person asking for revenge or asks for revenge based on false information, is still okay to exact revenge, well the show dwells into all of the morality of those questions and is not just a gore filled anime with no story. Only problem you may face is that names are a bit hard to remembers as old characters are referenced quite a bit other than that it is a great show.
