I watched the nighttime soaps and daytime soaps simultaneously in the 1980s/early 1990s and became aware of the differences that were necessary for their unique places in TV, even as so many people tried to put them all in the same box. Nighttime had the budget to do "better looking" stuff and of course had the larger following, but daytime had the luxury of time to play out many more story beats and develop characters further.
I think those who grew up on "never-ending" daytime soaps (and became accustomed to their techniques) understand better that you have to have a fairly large number of "unhappy endings" for the characters, but that these are to be expected, since real life isn't always happy. It is rewarding to the viewer, however, to watch those characters recover from bad events and become stronger, maybe even happier. It gives the viewer a sense that they're "along for the ride" with that character. It was also understood that a happy, unconflicted character on a daytime soap was a boring character who was likely to be written out because the writers had run out of ideas for him or her.
The final scenes of NuDynasty didn't make me think everyone would be living happily ever after, though having some key events occur like Lauren's birth and Steven's return made it feel that there would be a bit more love in the air. They made sure we knew that Alexis and Dominique would still be sniping at one another, and that Blake, Cristal, and Fallon would all be elbowing each other at times where Carrington United was concerned. I think they wanted the viewer to come away with the feeling that they'd continue to be more or less like they've always been, but that some ongoing issues had been overcome that might allow them to move forward with less conflict than before. The three characters who had been most at loose ends---Kirby, Sam, and Culhane---are all now in committed relationships, and the extraction of Adam from their lives could only help the family move forward. The looks that I saw Blake giving Alexis during their search-and-rescue mission (respect for her tenacity and determination, maybe even a bit of admiration for just how far she'd go to save Dex) gives me the feeling that he now has a more positive
view of her after all this time. This will certainly help them tolerate one another in the future.
