Netflix’s latest foray into adult animation, the steampunk Western Bass X Machina, has achieved a rare feat following its November 3, 2026, premiere. The series debuted to a perfect 100% critic score on Rotten Tomatoes, drawing immediate comparisons to the gritty frontier drama of Yellowstone and the stylized, genre-bending energy of Cowboy Bebop.
The series, created by LeSean Thomas (known for Yasuke and Cannon Busters), reimagines the life of historical lawman Bass Reeves within an alternate-history frontier. While Taylor Sheridan’s 2023 series Lawmen: Bass Reeves focused on a traditional historical lens, Bass X Machina leans into speculative fiction, outfitting its protagonist with a cybernetic arm and placing him in a high-tech, lawless wasteland.
Brian Tyree Henry stars as the voice of Bass Reeves and serves as an executive producer on the project. The cast is rounded out by Janelle Monáe as Glory Reeves and Tati Gabrielle as Dana Starr. The production is handled by South Korea’s Studio Mir, the acclaimed animation house behind The Legend of Korra and Netflix’s Devil May Cry.
Why Critics Are Drawing Genre Comparisons
The “Yellowstone meets Cowboy Bebop” label stems from the show’s specific narrative structure. Like the 1998 anime classic Cowboy Bebop, the series utilizes an episodic bounty hunter format where high-tech gadgets coexist with a “used-future” aesthetic. This sci-fi layer is applied directly over the harsh, moral ambiguity and survivalist themes typically found in modern Westerns like Yellowstone.
As of November 4, the 100% critic rating reflects a consensus on the show’s visual ambition and its successful fusion of Western tropes with steampunk technology. While some early reporting online incorrectly suggested the series might land on Prime Video, it is a confirmed Netflix Original and is currently available exclusively on that platform.
According to Bass X Machina’s production details, the series serves as a major collaborative effort between American creative leads and South Korean animation talent, marking another high-profile entry in Netflix’s growing portfolio of mature-rated animated content. The “rare” score puts it in an elite category of streaming debuts, particularly for a genre-mashing title that relies heavily on stylized action and alternate history.
The series focuses on Reeves as he navigates a frontier where steam-powered machinery has accelerated the industrialization of the West, creating new types of outlaws and mechanical threats. This setting allows the show to explore the historical significance of the real-life first Black U.S. Deputy Marshal west of the Mississippi River while utilizing the freedom of the animation medium to introduce supernatural and technological stakes.
