Power of Spiderman

I wonder how much the success of Spiderman is being driven by kids. In the 4th and 3rd grade classes where I've been student teaching, the kids knew the exact date of the movie's release weeks ahead of time. They would ask me what I was going to be doing on May 4th back in mid-April! And two students were pulled out of class early that Friday so that they could go to the movie with their dads! I think these kids have grown up watching the first two Spidey movies over and over on DVD and so they'd built up this huge excitement over the coming movie, which might often be reinforced by superheroes being a way to bond with Dad.
