The idea of this book is nice, but I wasn't able to appreciate the execution. My biggest issue is the combination of the text and images.
The layouts are messy, some illustrations are not on the same spread as the text they are meant to accompany. There are also pictures re-used in smaller versions...I guess to try and punch up the pages of just text. It would have been better to shorten the story, particularly the review of how the cat works, which we see as the professor creates the bionic cat, and again as he explains things to the boy he made it for.
Also, the text and illustrations don't seem to have been created for the same age groups. The illustrations are fine for young kids, but the story is too wordy. Older kids could appreciate the story, but might be turned off by the 'cutsy' illustrations.
It feels like a book created by people wanting to fill a niche, and for those wanting to read in that niche it serves it's purpose.
