The antagonist isn't terribly interesting, but the dynamic between Damian Wayne (Robin) and John Kent (Superboy) is what makes this book work so well. Tomasi has been writing Damian for years and knows how to bring out the best in him, and John's an incredibly likeable kid. They exemplify the best (and worst) qualities of their parents and the kids' relationship to each other mirrors their fathers' in a lot of ways. They're great contrasts to one another and their conversations and jabs at each other are super fun to read. The art is great too. This is some of my favorite work from Jorge Jimenez. If you're looking for a DC comic appropriate for young readers (I'd say maybe 12 and up?), I'd strongly suggest checking this book out.
