Things I liked:
- Original content was treated with a remarkably high level of respect. The intent of actions remained the same as the first author's. Modifications were only made in places where it would add to the experience and place it into the zombie-stricken world it was now set in.
- Some characters remain exactly as you remember them, but others are transformed in ways that seem appropriate somehow. Darcy is a skilled zombie-fighter for instance, but Bingly is not. Like I said, appropriate, somehow.
- Well, duh! Zombies!
- Ninjas. Why does every author insist, because there are zombies in a book, take it to mean that every ridiculous pop-fiction entity be included. If you want to have the characters having been trained in the orient, fine. But are so many ninjas absolutely necessary?
- Few changes to the development of the story. This is a two edge sword. Some changes of events should have transpired due to the fact that people are dropping left and right to the zombie menace. I half expected this to be a total rewrite consisting of what the characters would have done, had there been zombies at the first ball. But instead it was a retelling of the same events with different setting. Not bad, necessarily, but unexpected.
