I agree that's why it feels like this Cristal is doing something wrong. Being bitchy goes against that sort of quiet strength you mention. She went with her gut and didn't make a scene about it, she just quietly did the right thing. No bitching, no scheming, no theatrics. This Cristal is all wrong and it feels like the actress could actually play her better but is being directed and told to do it a certain way and that's sad. But that's also history kinda repeating itself.
Krystles, in her earliest incarnation during S1 and S2, and Linda Evanses are just hard to come by -- which is one of the things which made the original DYNASTY so promising (and no doubt why I start so many threads about Krystle and what they coulda/woulda/coulda done with her... Linda, by the way, had the same frustration).
I don't post all that much about Alexis because although equally well cast, and an unusual example of an actress who could both play a great dragon lady bitch
and was genuinely beautiful, they mostly did with Alexis what was possible (although the writers fell short even for her). They came closer to fulfilling her potential, because the brass "got" the villain concept.
And then there was the yin-yang chemistry both actors brought it (that's an Aries Rising-Scorpio Rising dynamic, but I digress).
That's what really made oldDYNASTY so special -- or, at least, almost did. But the writers proved they were every bit the hacks as those writing the new show (and maybe worse). And so they ruined it by turning a character they did not understand, Krystle, into exactly the sniveling and squeaky goody-goody that Alexis said she was (but Krystle had not originally been) ignoring Krystle's intelligence and her intuition (and even that goodness itself) as she arranged flowers, said absurdly naive things, and didn't have a clue as she'd cock her head to the side once again and moan "Darling!" in lieu of an actual storyline.
At least Season 9's medical storyline allow us to forgive all that, slightly, as a kind of retroactive foreshadowing.
Today, of course, they still don't understand a Krystle. So all they can do is look back at Linda's character from the '80s, proclaim her "weak/eye candy/trophy wife" and make the new incarnation, Cristal, a grasping bitch more like Alexis, but one who will occasional break character and say something maudlin and pro-family here and there so we'll know she "has a heart" despite her saying it in vocal fry, the irony of which will lost on all participants.
