Neither dark nor black... Yawn.
Spoilers ahead.
I actually expected something good of it. I like dark animes, I like good storylines, I like interesting characters. And none of them made any appereance in this show.
I mean, the original idea was OK. But then the plot looked more like: a baddie comes, we have to kill him, another baddie comes, we have to kill him... And that goes on and on and on.
And all the characters are so empty and I really couldnt like anyone at all here, maybe except for the cat (surprisingly, the only one without his past life being displayed, maybe that saved him from being so cliche! All the other characters and their horribly-stereotypically-cheesy pasts were not more interesting, but plainly boring).
I know the creators tried hard to make the characters cool and intriguing, but to be fair I was just laughing at the pompuous dialogue they delivered most of the time (specially the kid in love with Amber, PLEASE, so much cheese stuffed in so few lines!)
