TJ has posted, so my initial comments now seem a little out of context.
Ref. the overriding thread theme: from my perspective, I like realism in characterisation, probably to my detriment, and I sometimes wonder if, actually, the female portrayal is more true to life. By which I mean, when presented with danger, how many of us would pick up a sword - in whatever fashion - and face whatever disaster might cometh. I'd run a mile, with most of the blokes I know would be out the door ahead of me.
I think there is a focus on portraying a real male as a hero. To have one who has doubts, worries, who is concerned with survival and saving their skin (who might even, whisper it, scream...) seems to go against what we want. And this is much to the detriment as there is then a vast gulf between the often slightly less than real life female, and the often much more than real life male.
In terms of female protagonists, there are loads in mainstream literature who are fabulously well realised and rounded: Scarlett O'Hara (who didn't run around waiting for Rhett, or even Ashley, but instead pulled down the curtains and used her womanly character to make the best of things), Scout in to Kill a Mocking Bird, Daisy in Gatsby - who was stronger than her husband (Fitzgerald is good at women, although he does dais-them a bit), and plenty more.
So, is is a SFF thing? Do we want a needy woman to be rescued. (not keen on it, here, but it seems to be a standard sometimes.) And do we want a man to do it? Personally I tend to fight against that trope, and applaud those who do.
