I like the inclusion of Combat, Habitat and Society, and Legends and Lore with the monster entries, but I dislike the formatting of the monster stat blocks. Its very much a return to 3e style monsters, with special abilities separated from the stat block, and a few of the monsters using the spells from the rules.
The character sheets are alright for showing you wear they got each piece of the character, but for actual play I think they're going to be less useful. For instance, the rogue's thieflike skills are on the second page, since they come from his scheme.
