What hate?
This.
I actually love this series, but I won't deny it has some flaws, mainly that all the promising twists and turns of the story turned out to be somewhat weak and boring and generally more like one would expect it from this kind of series, in particular the thing with the souls of those who were "sacrificed" returning back to normal. Not to mention that it looks like they managed to ruin the relationship between Jack and Carly (aka "Retributionshipping") by bringing her back to life and have her remember nothing from when she was a Dark Signer. Which on second thought doesn't entirely make sense, because she came to the realization that she fell in love with Jack BEFORE she died.
Oh yeah, and Aki gets more and more like the other primary female cast from the previous shows, pretty useless. She was such an awesome character but they reduce her to almost nothing now.
