My overriding memory of Wonder Woman, never having been a comic reader, is the 1970s TV series starring Lynda Carter, which I grew up watching. Now that was cool. But given the era, I don't think there was much emphasis on Wonder Woman's feminist side. Certainly, there was a lot of emphasis on her sexiness and there were an awful lot of dads (as well as sons) who fancied Lynda Carter rotten. But given the boob tube, shorts and knee-high boots worn by the gorgeous Lynda, rather than just drawn in a comic strip, who could blame them?
I don't think much has changed these days, either. You only need think of the utterly self sufficient but surprisingly scantily clad Lara Croft, or even the groan-worthy but addictive Xena: Warrior Princess TV series, to realise that, in the world of media at least, female strength is often painted hand-in-hand with sexiness.
And the same goes for (some) men too. The sister series to Xena: Warrior Princess, Hercules, starred the lovely Kevin Sorbo. Not only was he super strong, but his sexual image was all-important too. The long hair, the blistering smile, the muscles, the tight leather trousers, the sexy wristbands--all of this aimed to seduce the watcher.
So perhaps strength and sex simply are natural partners. Maybe we just do find someone--man or woman--who is in control, masterful, and their own person inherently attractive. And maybe the issue of feminism is irrelevant here, or a side issue at best.
