It wasn't completely ignored, but I have a little bit of a chip on my shoulder that Apocalypse Hotel didn't get way more recognition than it got. Should've won all the awards.

Going back a little deeper, I can't pretend to be surprised that Akagi isn't mainstream, but Kaiji by the same mangaka deserves more popularity. It's a tragedy that the anime ends at part 2 when part 3 was the peak.
