I understand that this is a book for kids. However, I don't understand why that means the characters have to be changed to fit what kids like to read these days. I didn't find Barbara and Tim believable. Just because the book says that's what their names are, doesn't make it them. In the book Barbara and Tim are at a Halloween party, and Barbara makes a comment that makes you think that she would rather leave Tim at home because he's younger, and that automatically makes him lame. All I ask is if you write a book about Batgirl and Robin for kids you actually try to make it seem like that's who you're writing about, and not in name only.
