I am also not too impressed with the change to the Atlanta locale. It seems like everything is getting filmed or set in Atlanta nowadays - a little overkill. With the campy nature of NuDynasty, I’m surprised we haven’t seen any Real Housewives cameos or a Walking Dead theme party at the Carrington mansion - maybe in the future, NuCristal can dress up like Walker Celia-Cristal. Speaking of Real Housewives, I’d love to see Lisa Rinna do a stint on the show as Alexis’s nemesis Tracy Kendall given the fact that Lisa is married to Nicollette’s ex-husband Harry, but I doubt that would ever happen - would definitely raise eyebrows and possibly bring a little publicity to the show. In any case, with the tech migration driving downtown Denver's resurgence, as well as the resurgence of oil and gas drilling in Denver, there wasn't really a need for a shift in location, but I digress.
Notable changes to me:
In the pilot for original Dynasty, Krystal had many friends and coworkers that seemed to support her engagement to Blake and she promised them that after her marriage, she wouldn't change and would invite them out to the mansion - something we know didn't happen. I think if we had gotten a glimpse of that same support by friends for Cristal in NuDynasty, there may have been a little more empathy for the character in the beginning. However, the fact that Cristal was actually a woman named Celia pretending to be "Cristal" may mean she did not get close to too many people for fear of her true identity being revealed. I see no indication yet of the character Mark Jennings (or alternate counterpart) who was also responsible for saving Alexis and Krystal in the original cabin fire, but perhaps he's being reserved for NuCristal. However, Nick Toscanni has been cast for Season 2.
Speaking of the cabin fire, when we saw Blake and Cristal visiting the Carrington cabin in earlier episodes of NuDynasty, I thought perhaps it was a foreshadowing to a future scene with Cristal and Alexis trapped in a cabin fire similar to the fire at Steven's cabin in original Dynasty. Instead, we got a fire in the stable house during the finale with other characters (including Alexis). The finale also included a scene between Cristal and Claudia involving Matthew and a gun that ended with Cristal being shot and Claudia realizing he truly was dead. Original Dynasty had an episode with Claudia intercepting a fax that revealed Matthew and Lindsay were in a car accident that had no apparent survivors. When Claudia found out that Cecil knew they were dead, she planned to shoot Cecil, but when Krystal arrives, they struggle over the gun and Claudia gets shot. Also alternatively, a few seasons later, Claudia dies in the fire she started when trapped in her room at La Mirage, but in NuDynasty, it is Claudia who shoots Cristal (who had been trapped) and leaves her to die prior to the fire in the stable house.
Then, there’s the Ted, Sammy Jo, Claudia, Adam, and Kirby character and timeline changes. In original Dynasty, Ted had already died at the end of Season 1 before Sammy Jo came to town a few episodes after Alexis in Season 2. Whereas, in NuDynasty, Sammy Jo arrived before Ted and Alexis, and Ted is still alive. Claudia was pregnant by Matthew instead of already having a grown child (Lindsay) with him. Instead of Sammy Jo, Melissa is the one pregnant by Steven and not trashy like original Sammy Jo. Alexis is more like a combination of original Alexis and has elements of trashy little tramp Sammy Jo. Also, in NuDynasty, the Adam storyline begins and Kirby shows up at the end of Season 1 vs. Original Dynasty when Adam (Michael) shows up at the beginning of Season 3 and Kirby shows up around a third of the way through Season 3.
In original Dynasty, Joseph seems to have followed Alexis's life through the tabloids since she was banished from Denver, but never seemed to be a fan of hers and dreaded the day she would return to Denver. Ultimately, he was the one responsible for the cabin fire that trapped Krystal and Alexis due to the secret Alexis kept over his head about Kirby's mother. In NuDynasty to date, he hasn't shown as much contempt for Alexis as the character did in the original.
The complete Colby family rewrite - not going there.
I'll think of more...
