Starring Alexander Skarsgård as a heavily armored, helmet-clad “Security Unit”—who has to hide the fact that it’s no longer under corporate control, lest it take a one-way trip to the deadly “acid baths” for recycling—the series walks a sometimes idiosyncratic line between comedy and much darker ideas.

Based on Martha Wells' novels 'The Murderbot Diaries,' 'Murderbot' follows a rogue cyborg security robot protecting a crew of nonviolent scientists.

Despite the elegant production design and admirable effects, "Murderbot" feels like a sci-fi comedy still searching for identity.
