3,5 stars. Calling this book Men Of Letters Beastiary is a little misleading. It's more like the Sam and Dean version of John Winchester's journal. Which isn't bad. But not what I expected. The illustrations are beautifully done and the annecdotes are funny, I smiled at most of what's written from Dean's point of view. Correct me if I'm wrong but I think this book isn't really sure which season of the show we are at when reading it. Some of the information isn't up to date with what happened in season 12, some of the information is. But if you're a fan of the show and want to relive Sam and Dean's biggest hits, this is your book. If you want something Men Of Letters-ish... it's not.
