Well, that's a good point. And those are good examples. I notice almost all are either products of the past or were set in the past. But it could still work today.
(BTW Wynona Ryder, as Jo, did not wind up with Christian Bale's Laurie -- he married pretty Amy. Just read something about this a couple of days ago. Apparently Louisa May Alcott -- who, when I toured her home, I pretty strongly suspected was gay, and certainly a proto-feminist -- was averse to marrying off everyone as it was, but her publisher forced her.)
I'm trying to picture how
Broadcast News would look today. OK, I can see Rachel McAdams, or maybe Ann Hathaway, playing the Holly Hunter role, and maybe Zac Ephron, or maybe one of the Hemsworths, as William Hurt. It could work!
But the fake news would have to be way more shocking than the shedding of a tiny insincere tear. Rachel McAdams would end the relationship after discovering that Zac Ephron planted a story about Hillary Clinton running a child sex ring out of a pizzeria.
