I see it as a potential perk of Goyer accelerating the Clois relationship's development.
For people who want to see children arcs done well, I recommend the show Six Feet Under.
I'm not sure why the parenting dynamic requires better writers in and of itself... I think all fundamental relationships require good writers, from first love to siblings to everything in between.
It requires better writers because there are less cliched tropes to fall back on. Less cheats.
For centuries, narratives have followed certain formulas. That's why we are often told that it's "hard" to write narratives about married couples vs. the concept of falling in love. Well, it is harder. But one of the reasons it's harder is because for years and years we got stories where women were basically treated as the "prize" that the dude wins at the end of the story so all of these cheats and short cuts about how you tell that kind of story became part of our collective consciousness. So when writers have to break out of that box and go in a different direction they find that the "cheats" they have relied on for years and years to create drama and conflict are no longer available to them.
That's why I say it requires better writers. Because it does. It requires writers who are willing to look beyond the "cheats" and short cuts of drama and look deeper.
