Closing thoughts. The artwork is black and white and ranges from meh to pretty good. Layout and editing is good, there was a few errors. But that is to be expected to a point in a book this large. There was a few stat block aspects that don't fit the Pathfinder formula, personally that doesn't bother me as I consider them more a rule of thumb than absolute rules on monster creation. The CR's for the most part with out play testing them look fairly good, there was a few I thought maybe should have been higher or lower, but hard to say with out using them first.
I will be honest I find reviewing monster books fairly hard. I am not a huge number cruncher, which makes it harder for me to notice them. I tend to pick some at random and check them. Also it is hard to truly judge a CR with out playing with it first. As far as the monsters, some I thought was pretty cool, some I was meh about and most where pretty good. So what's my rating? Well this is more based on personal opinion that most of my reviews for the reason given already, but I am going to personally give it a 4 star review.
Trust me, I'm a Succubus.
