It seems to me that almost any fight, particularly comic-book fights, superhero fights, action film fights, would be shorter, less flashy, and more successful for whoever undertook the final move, if the person determined to win focused almost solely upon kneeing their opponent, hard, in the groin.
(I am reliably informed by those whose business it would be to be in the know that even wearing a cup is not necessarily proof against such a move, given that kicking, punching, or otherwise banging a cup hard enough would cause painful repercussions inside the cup.)
This might not work as well against a female opponent, I'll grant you. However, having landed on the cross-bar of what was once called a boy's bike more than once myself, and having experienced the breath-stopping impact of that, I'm willing to bet it mightn't be as ineffective against women as all that.
As you can imagine, this has lessened my appreciation of even the most gloriously choreographed fights I've witnessed on the big or small screen lately.
