Watch Marshals streaming in the
Marshals is a 2026 CBS drama and Yellowstone spinoff that follows Kayce Dutton, played by Luke Grimes, after he leaves the Yellowstone Ranch behind and joins an elite unit of U.S. Marshals in Montana. The series leans into a western-crime format, pairing Kayce's cowboy instincts with his Navy SEAL training as he and his teammates confront violent threats across the region. Alongside the casework, the show emphasizes the personal cost of the job, as Kayce must balance family ties, duty, and the pressure of serving as a last line of defense in a dangerous part of the state. The cast includes Logan Marshall-Green, Arielle Kebbel, Ash Santos, Tatanka Means, Brecken Merrill, Gil Birmingham, and Mo Brings Plenty.
Early reception for Marshals has been mixed to moderately positive, with critics appreciating Luke Grimes' fit for the role while also noting that the series stays close to familiar procedural territory. Rotten Tomatoes currently lists the show at 47% on the Tomatometer, with a much softer 32% Popcornmeter, suggesting that viewers and critics are not fully aligned yet. Metacritic's coverage reflects the same split: one review describes Grimes as capable of carrying the Yellowstone offshoot, but also calls it a very familiar CBS-style action procedural. Another notes that the series is still mired in Yellowstone lore even though it presents itself like a case-of-the-week drama. The general takeaway is that Marshals has a strong central star and an appealing western setup, but some critics feel it is still searching for a sharper identity beyond franchise familiarity and broadcast-police formula.
