This review will be for the series as a whole:

Arguably, this is Urasawa's magnum opus.

A sweeping story told over the course of decades about childhood nostalgia, the complexities of growing older, and the social forces that shape who you become, all wrapped in a mind boggling mystery that will keep you hooked until the very last panel.

Here, Urasawa's art style is perfected. Every pen stroke is precise and useful, to a degree that is almost, but not quite, minimalist.

His trademark storytelling style, which utilized all the tools of non-linear storytelling, effective redirection, and constant intrigue is put to task like a machine in this series.

In this story, you will find tales of dangerous apocalypic death cults, UFOs, schools for psychic children, and a homeless God. In spite of its scifi weirdness, it is also a story that is consistently rooted in its characters.

If you haven't read Naoki Urasawa before, do yourself a favor and see what this legendary artist has to offer.
