There are a number of angles you could use to approach Gankutsuou. You could talk about the studio, Gonzo, although that conversation would end roughly where it begins – Gonzo have barely created a handful of noteworthy shows over their career, and Gankutsuou’s director isn’t particularly tied to that studio. You could talk about that director, Mahiro Maeda, whose career has spanned early Studio Ghibli, a variety of guest positions on shows as varied as Giant Robo and Kill la Kill, and who has seemingly joined many frustratingly talented creators at that great Studio Khara in the sky.
Or you could talk about the fact that Gankutsuou actually has source material.
