I've thought this whole show is similar to Dallas. Instead of the family fighting ith each other for control of Ewing Oil, and protecting it from outsiders, Yellowstone is doing the same with the ranch.
John = Jock - the patriarch
Beth = JR - ruthless and wants control
Kaycee = Bobby - spouse (Monica/Pam) wasn't initially welcomed. The good guy.
Jamie = Gary - pushed away by most of the family
Chief Rainwater = Cliff Barnes - trying to get back what was taken from his people
Rip = Ray - characters aren't quite the same, but both are the ranch foreman
Still need a Sue Ellen and Miss Ellie.
That's a pretty good comparison actually but not sure Beth is really the true JR of the family. She is in some ways similar to JR because she is ruthless but she isn't fighting for control from John/Jock or Kayce/Bobby like JR was with trying to gain control from his family while Beth is fighting with her family to keep what they have not against them. Jamie kind of has turned against his family now but he is in no ways a ruthless evil villain like JR so yeah he is kind of like Gary. In the reboot it was very apparent that it was family vs family with Bobby and Christopher on 1 side and JR and John Ross on the other.
