From the lead paragraph of Ebert's review of the film "Haywire:"
There must be Freudian insights explaining why so many young males respond positively to superwomen as heroines.
At science fiction and comics conventions, a woman wearing a fetishistic superhero costume will almost certainly be the focus of a circle of intent fanboys.
Maybe there's the prospect of an all-protecting mom.
Or the promise of a cool female buddy.
The possibility of sex seems to be secondary.
