Pros: Another affordable, optional mini supplement for CAH. Horror wasn't a huge deal in 80s cartoons, but present enough to warrant mentioning. This book covers the obvious (gore and death), while also providing a nice checklist of horror locations and suitable badguys. A Ghostbusters-but-not-really setting rounds the book out, and is incredibly useful because of the stat breakdowns over various monsters for use or inspiration in your own games.
Cons: Not much, really.
Overview: While the supplement does hit the common sense stuff again, the price is more than justified with the stat writeups for various monsters for use in eyeballing and making your own beasties in the game. The horror guidelines are very useful for getting the feel without crossing the line. Very nice product for CAH.
