In the four years since its premiere, Taylor Sheridan's Yellowstone has become an entity in and of itself, a hit series that spawned not only a successful spinoff in this year's 1883 but a verifiable television universe now with a sequel show, 1923, to follow next month. Like the fictional family whose domain exists over significant swaths of Montana, Sheridan has solidified a true TV empire that rivals the likes of Succession, Dallas, House of the Dragon, or any other series you can name that revolves around a dynasty.
