Query: Polar Express: Yet another boy's tale.

Have we learned nothing from the 60's and 70's studies of childrens' books? Studies that showed that most children's books, and textbooks, had boys as the heroes, as the active ones, while girls and women were relegated to minor 'helping' roles. I was about to buy this book for my 5 year old granddaughter, but when I read that it was just another story about a boy and his quest for whatever, I decided not to buy it. Where are the millennium's great stories with girls as heros? About a girl's quest for knowledge and wisdom? Oh bother! I won't be shelling out bucks for this one. How sad.Barbara Hendryson, California poet and writer.
