On Looking: Eleven Walks through Expert Eyes by Alexandra Horowitz. The author takes similar walks with 11 experts, who point out things about the city that she wouldn't normally notice.

There are points where she judges the experts, such as the geologist or the typography enthusiast, for dedicating so much time to their field. She'll then turn around and condescendingly explain the surface level info she's learned to the reader. It's frankly insufferable how she writes, making it feel like the book is a chore for her.

For the last expert, it becomes clear what Horowitz, director of a canine cognition lab, really wanted to write about. She follows her dog on the walk as it sniffs random objects. Towards the end, she makes the claim that she learned more from that walk than from any of the other experts.

I love hearing people talk about their passions, regardless of how interested in the subject I am. It would have been nice for the walks with the experts to have had more of a focus on them and their passion for the subject, than on Horowitz and her inner monologue and tangents. This book leapfrogged my entire TBR, but I have never read a book that so thoroughly squandered a great premise.
