Since its debut in 2018, Yellowstone has become one of the biggest and most influential series on television, yet the show's future lies not in continuing the original story, but with its many successful spin-offs. Following the trials and tribulations of the Dutton family, Yellowstone and its supplementary shows take an uncompromising look at life in rural Montana, never shying away from brutal depictions of the physical and financial threats that fill the state. However, while the main series has consistently focused on patriarch John Dutton and his children, the franchise's future actually lies elsewhere.
