That they already know all about the lack of agency of housewives or pleasure bots or the centrality of women’s fertility to their social value … because they live it, and are busy handling it IRL and this film isn’t really helping anything.
Except, as your last sentence mentioned, it is good for men to see the issue portrayed, from both sides. That’s not nothing.
Edit: those are some great examples like Ripley from Alien and the wife from the Shining who did similarly, but by a different means. The former shows the girl boss who while being a woman fills roles that historically were more thought of (even by women) to be held by men, whereas BR 2049 made it even more personal by having the main character be an actual man (sort of:-P), filling roles that historically perhaps women were more known to be in.
Ofc not every film is going to be enjoyable by everyone - some may not like it purely for the use of neon coloration, or for the sadness of it being dystopian. And the lack of agency is depressing to see.
