I thought the original Zoo was pretty stupid, but it did at least have some thrilling scenes of animals attacking people, and the science behind the animal attacks was goofy but plausible enough for purposes of this sort of story. Zoo 2 is just incredibly stupid and pointless. I think the Bookshots format makes it suffer, because it means the story has to rush along, except even then the pacing is awful. There are some interesting ideas mentioned, like Chloe and her son getting kidnapped by Friends of the Earth that welcome the animal attacks, and even the basic premise of feral humans could be kinda neat. However, the feral humans don't even appear until page 50 of 146, and they're never given enough of an explanation or basis in the "science" of the animal attacks. Also, from the back cover blurb, I was expecting these to be some sort of human-animal hybrid physically, whereas they're basically just throwbacks to when life was nasty, brutish, and short. They're just zombies, except we never get an explanation of where they came from or how the infection spreads, and the "cure" is total nonsense. I was also incredibly bothered by how much of a sexist asshole Oz is here. He leaves Chloe and their kid in France, which isn't any safer than where he's going and is ridiculous because she's a scientist too. When a new scientist is introduced, she exists only for Oz to think about how sexy he is but he can't possibly do her because he's married. The plot and characters are deeply stupid, and the rushed nature of the story means that things that should be given time, like figuring out what's up with the new feral humans, is just skipped over and ignored. I expected this to be a goofy waste of time, but I'd hoped there might be something fun or exciting in here. Instead, it's just crap from start to finish. Whether you enjoyed the first Zoo or not, definitely skip this one - it's absolutely not worth wasting your time on, no matter that it'll take only two or three hours to read.
