I like the series Cobra Kai, a continuation of the Karate kids-movies. The series runs successfully on Netflix, 10 episodes per year. I think something like that would have been possible for Dallas, but it wasn't meant to be
Just saw this comment and wanted to concur, as I am a huge fan of Cobra Kai. I grew up on the Karate Kid films, even started taking Karate classes after seeing the first film (I dropped out after 3 months, though, it wasn't as fun in real life as looked in the movies). And when folks have asked me about CK, I saw the series better than it has any darn right to be. The creators of the show are hardcore fans of the films, and it shows in the care that they put into the storylines. They've said in interviews that they consider the films to be their "Star Wars" in terms of impact on their lives, and that they'd privately been talking about how they revive the franchise for years just for fun (like we do about Dallas here) before they actually got the opportunity.
In my opinon, the series straddles the perfect line between revisiting the past and moving forward, attracting both old and new fans equally. It's got many of the older original cast back, appealing to use Gen Xers and Millennials who grew up watching the films either when they debuted in theaters or in the ubiquitous reruns on TV, and it's attracting the young Zoomers, as it's creating interesting new young characters for them to relate. I participate on the fan forum on Reddit as well interacting on Twitter, and the age-range is from teens to 50's, and I'm frequently seeing fans posting about how they discovered the TV series (especially once it moved to Netflix, a much broader reach than Youtube) and loved it without ever seeing the movies which they went back to watch after.
And that's the key for modern show like this. The writers have all sorts of Easter eggs and callbacks to the films, some blatant some more subtle, so if you saw the films you'll get it , but they're not absolutely required in order to follow along and enjoy the show. Plus they also occasionally cut in scenes from the films, to use as flashbacks. And from the start the premise was nice and simple, you had two guys, a bully a nerd, who fought in High School, 34 years later the bully is a loser while the nerd is rich and successful, so the bully is trying to get his life back together while coming into contact with the nerd who still resents him from the past. Conflict ensues. And it works.
They're also wise in how they bring back and utilize older characters. Just like I saw with many Dallas fans here, I've seen older fans who impatiently want all their favorite character brought in as soon as possible, and want them all to be a regular character on the show, and be connected to the new characters (there's tons of speculation and "theories" about certain young characters on the show being the secret child of some of the older characters, even though most of the theories make no sense), but the writers said they only want to bring characters back when it's logical for the story they're telling, not just to show up for random cameos or try to force them into roles they don't fit. So like the ex-girlfriend from high school of the two leads was teased since season 1, and then finally showed up in the last couple of episodes of season 3, and IMO she was used perfectly. She was basically the catalyst to get the two leads to finally stop fighting and realize that they needed to get over their high school feud once and for all, and then she left again. Before that there were some fans who actually wanted her to get back together with one of the guys, so they could fight over her again, but I don't think that would have made sense for any of the characters. And I'm glad the writers know that and they avoid those type of easy fan-servicey stories. And it's that type of approach that I think the Dallas continuation needed.
