The illustrations save this book. It's a really attractive books and the illustrations and drawings are colourful and joyful.
The writing is... so-so. First, it's solidly aimed at men: Kalda doesn't even pretend that women might read this, and he often breaks the fourth wall to talk to the reader man-to-man about the hidden manliness of preferring cats over dogs. Kalda is an illustrator by profession, and perhaps that accounts for writing that attempts to be chatty and witty but fails just short so that there are moments that feel awkward.
The profiles don't really share anything new or even biographically informative, but they are somewhat interesting. Nonetheless, as I said, the illustrations and quote typography are the thing here. The book shines from this perspective, which is why my rating ends up at 4 stars.
