It's interesting re-reading this after watching the movie based on this book and comparing the two. This book's biggest shortcoming is still Billy Batson himself. I'm not opposed to a version of the character who's kinda bitter from bouncing around foster homes, but for the vast majority of the book he's completely unlikable. I think Geoff Johns was aiming to do a similar thing he did with Batman in Batman: Earth One, where the main character starts out in a more negative light but grows into the more idealistic version of the character readers are familiar with over time, but this book is too short to really pull that off without it feeling rushed. I still love the additions Johns has made to the lore with Black Adam and the Shazam family, but I don't think many people will enjoy this book for the reasons listed above and because the movie overall is just a much better product.
