Very interesting and novel content
Really loved the new take on Batman with him being the villain
So hey. This book features the worst possible ending to the iconically classic battle between Batman and the Joker. The one where he finally breaks Batman. The results are cataclysmic. This book is an amazingly disturbing read thing in to the ongoing I believe Dark Night Metal series, providing a deeper look into the Batman who Laughs.
It was awesome
It was a fantastic story of how evil Batman would be if he became the joker. One of my favorites.
