She's a movie star, looks are a big part of what she sells. She's operating in a patriarchal world that values youth and beauty.
She cannot grow old. Yet she also, apparently, cannot use surgery to keep her competitive in her world. Like others have said, she's damned either way.
This handwringing and 'it's so sad' chat from other 40 something women on the internet just contributes to the problem. Our opinion is totally irrelevant. It probably only serves to make her feel bad.
It's the Hollywood execs who count. I bet they're mostly men. They're just focused on selling movies.
To change this would involve overturning highly ingrained cultural attitudes (youth is highly sought after when assessing female beauty) that have existed for millennia, for sound biological reasons.
RZ would be right to conclude that's beyond what she's capable if doing. In the meantime, she's just playing the game the best way she knows how. I say leave her to it.
For what it's worth, I thought she looked pretty good in BJB.
