Compared to recent works by the author like Chi no Wadachi and Happiness, his art here is very weak, as well as the story itself. Not least because this was one of his first manga so it justifies art to be weak.

Suspense exists, but the characters are totally stupid and do not act according to the situations, which ends up totally breaking the suspension of disbelief of the reader. It may even have the purpose of showing how humanity can be bad when there are no more rules or things like that, but everything is so gratuitous and unreal that this premise is broken.

The manga comes down to characters acting stupid at all times, cartoon characters taking unreal actions, gratuitous violence and rape all the time, with no context behind it. In short, a story that only serves to satisfy people with rape fetish and gratuitous violence.
