“Murderbot” might be a new term for some, so let’s break it down: It’s a Security Unit, or “SecUnit,” designed as a semi-organic robot with the primary function of safeguarding its designated humans. However, unlike typical SecUnits, this one—portrayed by Alexander Skarsgård—has managed to override its control system, granting itself autonomy from human commands. Taking the name “Murderbot,” it relishes this newfound freedom not by wreaking havoc but by indulging in an endless binge of streaming shows it now has access to.

When SecUnit is tasked with protecting a team of eccentric scientists exploring a remote planet, it anticipates a routine assignment where it can quietly enjoy its shows. But the mission becomes complicated when the team’s leader, Dr. Mensah (played by Noma Dumezweni), becomes intrigued by SecUnit’s atypical behavior. Meanwhile, the sharp-witted data specialist Gurathin (played by David Dastmalchian) suspects that SecUnit harbors secrets, potentially endangering the group by aligning with corporate agendas. While SecUnit indeed has secrets, they aren’t what Gurathin suspects. As threats escalate, SecUnit and the data expert must collaborate if they are to survive and escape the planet.

The story unfolds from SecUnit’s perspective, as it narrates events with witty commentary on human behavior, shares its thoughts, and occasionally showcases its favorite TV show, “The Rise and Fall of Sanctuary Moon.” This show—a campy, “Star Trek”-esque soap opera—features vibrant performances by John Cho, Jack McBrayer, and a stellar supporting cast.

One of the smartest things about the way Martha Wells tells the “Murderbot” stories, something the show quickly grasps and reflects, is the constant juxtaposition of disparate elements, all through SecUnit’s eyes. It’s a corporate product, and because of its TV addiction it’s constantly consuming other corporate products, but it’s also constantly on the hunt for emotional context. It finds humans disgusting and far too dependent on their feelings, and yet it can’t look away from the very real drama playing out in their lives. It’s not bound to obey humans, and yet it feels a sense of duty. These are all key to making “Murderbot” work as a series, and creators Chris and Paul Weitz seem to instantly realize their vitality, giving the show a very strong start.
