This is neither a great piece of literature nor terribly inventive. In fact, most of its characters don't come anywhere near to even reaching a third dimension.
However, because of the sheer amount of campy fun violence, and zombies, and some of the fast pacing in the book, and zombies, I liked it a lot. It's good for a mindless zombie blood bath, and not much else, but if you want some easy non-thinking book action, this book is perfect.
