4 out of 5 rating for Pathfinder Roleplaying Game: Bestiary 2
Good mix of old creatures and new entries, and balance between high and low CRs.
The art is inferior to that of the first (and third) Bestiary, but this is so useful that is arguably the second Pathfinder Bestiary you should buy after the first (ties with less useful but more artistic Bestiary 3).
Solid work, but not groundbreaking.
