I'd love to see a series exploring really any of the years leading up to the pilot. Maybe not the wildcatting days, since 'The Early Years' did that, but the 50s and 60s and earlier 70s - the years when Jock was running things and JR was on his way up, Bobby as the football star, skinny young Ray Krebbs showing up on the ranch with a note from his mother, the whole Gary fallout. With the right cast and production and writing it would be amazing. (What are the chances that would happen, though?)
The more I think about it, the more I would want to go with the concept of
@Taylor Bennett Jr. to create a series exploring the 1950s - early 1970s which Taylor describes as "the years when Jock was running things and JR was on his way up, Bobby as the football star, skinny young Ray Krebbs showing up on the ranch with a note from his mother, the whole Gary fallout. With the right cast and production and writing it would be amazing."
This idea of setting a modern day drama in the past was done by Mad Men with great success, as it set its show in the 1960s. So there's a precedent for that working with a 21st century audience. If that might necessitate making this Dallas more serious drama than soap opera, fine. I have no problem with that. Actually, the more serious drama style seems better accepted today than soap opera anyway. I just want it to tell great stories which would be fascinating to watch for people of all generations.
Another reason I like this is because the story of the years of building a company which becomes the largest independent oil company in the state of Texas would a compelling one. Dallas is already thought of as "an old show" done in old style, maybe a "dinosaur", so here they'd be acknowledging "Yes this is a show about events taking place a long time ago - we're embracing the idea of telling a story set in that time and turning what some would consider a possible weakness into a strength."
By doing that you also make it clear that the only way to do it would be with a new cast playing the same characters. It's not a stylistic choice to not use the still living actors of Dallas because it would be impossible for them to portray those characters as young people. I think it would help the audience accept new actors playing this characters because it would be so apparent to them that this story could not be told any other way.
It would be a great opportunity to look into things such as "what made JR become the man he became - what molded his character." Through flashbacks we could even look into how JRs childhood shaped him. We could see how Pam and Cliff's upbringing shaped their characters. I'd find getting the opportunity to watch all these personalities being shaped and to find out how different factors shaped them to be fascinating!
Seeing Jock Ewing working as a much younger man building his own company from the ground up and allowing us to finally see the way Jock Ewing did "bidness" when he was still in his prime years in a weekly series could be very compelling TV.
From a practical standpoint, a financial one, I think this is still the best way to do it. By making Dallas look like a 21st century show, conceding that an 80s soap is outdated, we'd be embracing the fact that yes, this is an old story, these events did take place a long time ago, but they make a compelling story to watch when told in a modern style!
