The Black Mirror was actually all kinds of wonderful, in my opinion. I've been so focused on doing all the others, the alternatives in the DC world, thinking that I knew my Supermans and Batmans from movies and tv, that I just never really considered, you know, READING them. 
 Silly me. 
 This was all sorts of creepy and fun. It's all about Grayson, too. 
 Now, I'll also be honest, I've also been becoming a superfan of James Gordon JR ever since I read about him in Suicide Squad, and seeing him shine in this volume was an especially good treat. 
 New and old villains share the spotlight, of course, and I'm always blown away by the joker who has gotten mightily creepy in his older age. Really fun stuff. 
 I'm thinking I might have to hunt around or ask opinions as to the best of the Batmans and Supermans now. I've avoid d them for far too long. ;)
