This is the exact sort of book I would have scoffed at before having children, thinking that no kid of mine would ever get obsessed with mass-marketed characters if I could help it.
And then I had a 4-year-old who, after years of not caring about superheroes in the slightest, suddenly decided this school year that they are fascinating. He has even gone so far as to create his own superhero alter ego (his name is Lightning Timer, and his power is throwing lightning bolts and making fire).
So this morning when we walked into the library and saw this book sitting on the New Picture Books shelf, my son's eyes lit up and he bolted straight to this book. He couldn't even make it all the way to a table with it, he just sprawled on the floor in the doorway of the children's reading room ecstatically flipping through the pages.
Of course we brought it home. It has been in our house less than 12 hours and already he has "read" it himself 3 times and had both me and my husband read a story. My story was really just a description of the characters, although my husband said the couple of stories he read were actually pretty entertaining. I have no doubt I'm going to have to end up reading the entire thing to my son, cover to cover.
He loves reading and will tell anyone who will listen that reading books is his favorite thing. But his joy upon finding this book goes above and beyond his already (very high) joy about books. I think this could be great for reluctant readers, provided you can overcome biases about pop culture characters.
