In the Russos I trust. IW1 was full of chicks and the biggest girl power moment came when they faced off against...another girl. So I'm not too worried that they'll suddenly switch gears and make IW2 all about third wave feminism or whatever.
I wasn't so much thinking of the feminist angle so much as simply the 'Superman' problem where one hero pretty much renders a bunch of other ones superfluous to requirements and could singlehandedly deal with most threats.
Thanos will give up when he sees her saving what she loves instead of fighting what she hates. Because if Thanos, a titan, can learn the value of human life, maybe we can too.
