Rating: WARTY!
I would have liked to have rated this positively. I like to do that with children's books, but although I hold them, in some ways, to a less exacting standard than I do more mature work, I cannot dispense with all standards, and I have to rate this one negatively because I feel it sends the wrong messages. I did like the beautiful art by Omar Lozano - bold, bright, and colorful, but the book isn't a coffee table book. It's supposed to offer a message, and that's where the problem lay.
On the one hand it features an African American kid, of which see see far too few in children's books, but having offered that, it makes the kid subservient to an heroic white guy. There are no heroes of color we could have chosen here? The first real problem, however, was that in his haste to be heroic, the kid abandons his breakfast, spilling the bowl and leaving his dirty dishes and a banana skin on the table. This is the kind of responsibility we want our kids to learn? Not mine.
Brushing his teeth is presented as one of the boy's greatest fears which must be overcome instead of, as it could have been shown, a way of adding to his super powers by protecting his teeth. Just as Supergirl is shown as Superman's assistant, the kid's little sister is presented in the subordinate position of bringing him his lunch box. Slavery anyone?
I'm sorry, but while I can see what was being attempted here, this felt wrong-headed in so many ways that I cannot in good faith recommend it as a worthy read.
