Fun for kids and those kids at heart!
Format: Paperback
When I was a kid around 8 or 9 years old, we would go to an outdoor theatre, a special treat. I remember the old 1960's era Batman movies playing on the screen. It was fun, exciting, heroic...all those things that made it pure enjoyment. When I think of recent Batman movies that have turned dark, deadly, desperate, all the fun has gone out of those experiences and I simply don't watch those movies. This is simply a long way of saying that this book, Bruce Wayne: Not Super, brought back all the fun I experienced as a kid. Here we have our hero, who doesn't think he is, who compares himself to everyone around him with supernatural abilities, and begins to grow desperate. The background story is essentially the same: dead parents, rotten town, etc. But we see life from his perspective and can root for him all the way. He goofs up, makes lots of mistakes and this makes him even more lovable. This book is prefect for readers young and old, and if this made into a movie, I guarantee you that I would watch it. Highly recommended.

Fun Story For Any Age Fan
Format: Paperback
Bruce Wayne is the only kid at his middle school without some kind of special powers. He wants to make a difference in Gotham but he thinks he doesn’t stand a chance compared to all of the other students with impressive skills. Bruce Wayne: Not Super follows Bruce’s journey to finding out what makes him special.
This middle grade graphic novel is very well done. I was already familiar with much of the author, Stuart Gibbs’ work. His style and sense of humor carry over well to this type of comic. The illustrations pair nicely and are done in a lighter style than more adult Batman comics.
Bruce Wayne: Not Super would be a good introductory book for younger Batman fans or a fun addition for collectors of any age to add to their stash.
I don’t know if the author has worked with DC before but I’d love to see more collaborations in the future for more middle grade graphic novels.
I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own. Thank you to NetGalley and DC Entertainment (DC Comics)!

Fun Middle School Origin Story
Format: Paperback, Format: Paperback
Bruce Wayne stands out at his middle school, Gotham Preparatory School for the Really, Really Gifted. No, not because of the wealth he’s inherited from him parents but because he’s the only one without any powers. But when he sees a student bullying another kid, he decides he has to do something. Will he come up with a plan?
This is a fun alternative take on Batman’s origins including cameos from other DC super heroes. The story was entertaining, and I laughed multiple times as I was reading. Be sure to look at the illustrations since some of the jokes are in there. This graphic novel is a very fun read.

Stunning graphics and a relatable hero
Format: Paperback
As Stuart Gibbs is one of my favorite middle grade authors, I was eager to pick up this book. It did not disappoint. Stunning graphics and a relatable protagonist make this an engaging read. Full of references to the world of superheroes, (some sneaky, some overt) there were plenty of opportunities to make inferences and share a snide chuckle with the author. This title is now on the short list for next year’s Battle of the Books in our school district. Kudos to Stuart Gibbs for the message of brain over brawn (and superpowers)!

Bruce Wayne: Not Super | Comic Review
Format: Paperback
I recently had the opportunity to check out Bruce Wayne: Not Super from DC Comics. The story is from Stuart Gibbs and the artwork is from Berat Pekmezci, and it is obviously about Batman.
The middle-grade graphic novel follows a teenage Cape Crusader going to school with every other DC character. Heroes and villains all going to school together is a funny concept that I think is pulled off well here.
What’s the joke about Batman? He’s just a rich kid with no powers, so what happens when he goes to a prep school with Superman, Wonder Woman, Flash, Green Arrow, etc.? Bruce has to come to grip with having no powers and how that affects his daily interactions with his classmates.
Bruce’s alienation at being powerless directly conflicts with his goal of being a vigilante hero for Gotham City. His camaraderie with Dick Grayson (Robin) helps him work through his feelings on wanting to be Ferretman Batman.
Aging adult characters down to young teens can come with their own difficulties, but I think Pekmezci nailed it. The artwork is very good throughout this book.
It may not be everybody’s cup of tea, but I really dig these “Elseworlds” stories that place the heroes in completely weird situations. And, what’s weirder than a middle/high school full of super-powered kids!
Clearly, I wasn’t the intended audience for this book, but I think those kids will have a great time reading this.
