I can now understand how an award-winning manga has such a relatively-low user score. I honestly want to rate it 1/10 because of how terrible the last four volumes are, but doing so would be a betrayal of how amazing the story was to that point in the same way the mangaka betrayed everyone who invested in this work before he gave them all the finger, so I won't. It's a 10/10 before that point.
Stop reading at the end of chapter 216 and imagine Hideo and Hiromi escaped to sea and there's an actual explanation for what's behind the zombie outbreak. The mangaka certainly didn't as he clearly hates himself and had no idea where this story was going.
