Ahoi,

so, with HXH about to end and having recently rewatched Shingeki no Kyoujin, I started thinking about it again. Gantz is, thematically, similar to SnK, except multitudes better. It´s gruesome, it´s full of cool action, it´s interesting. And, most of all, it´s concluded. No fear of filler, because you don´t know when the manga might continue. A studio could plan the whole thing from start to beginning, without any uncertainties.

So, why is it that nobody does it? Yes, there is the old anime that covered the very beginning of the story. But that´s it. It didn´t even reach the best parts.

Have there ever been any explanations? Or are there maybe actually rumors for a new anime version?

Seriously, Gantz simply seems to be a perfect match for the current anime Zeitgeist, it would be super popular. How come?
