While there are elements of fancy added to the characters, the basic story is, rather, basic. There's lots of reviews that compare this book to X-Men, and yes, that's pretty much it. More problematically, this reads like a child's story. The book is classified as young adult, and that appears to be the one constituency that is not served. The pictures are not as integral to the story as their volume might have one believe. It seems like Riggs often wrote the plot around the pictures, and that doesn't necessarily make for the best plot choices.
