PPZ has all of the major characters and events from the original book. In this version there are brain-eating zombies (unmentionables), and the Bennet sisters are ninja zombie killers. The focus is still very much on the gossip and dramas, but the storyline has sort of a dark comedy twist (not horror and not quite comedy either). The actual zombies didn't play as big of a part as I was expecting. It didn't blow me away, but I'm interested enough that I want to check out the movie.
