National quiz is quite a strange and unusual series.
The premise itself sets it apart from most of what is published. Japan is ruled by a quiz show, instead of some form of elections or stable government.
And what follows is a story that takes this premise and turns the world on its head, so that such an idea does not seem stupid at all.
While the story is intriguing and characters tolerable (well, portrayed but not especially deep, this is after all, not a psychological drama), what really sets this apart is the amazing art.
The world of national quiz has a lot of room of visual extravaganza
(with the show itself being flashy) and Katou utilizes this superbly. The art is slightly crazy, insanely detailed and quirky. The characters all look different and have very expresionable faces.
A very important point is that the art has strong lines, which with a comprehensing panel structure means you won't get lost on a page. And that you always know what exactly is happening in the picture.
This is, all in all an unforgettable masterpiece, that all people who are deeple interested in the medium of manga should read.
