Alien: Earth – Episode 4: “Observation” (2025) Review

 

Directed by Ugla Hauksdóttir, written by Noah Hawley & Bobak Esfarjani, episode four, “Observation,” pushes Alien: Earth further into questions of faith, biology, and human identity rather than focusing directly on the Xenomorph threat. 

The idea of synthetic adult bodies inhabited by the minds of children is unsettling, and the drama around reproduction and religion is well played—particularly by Lily Newmark as Nibs and Essie Davis as Dame Sylvia—though at times it feels more like a stage for ideas than an organic story. Nibs’ “level three event” mirrors Blade Runner, echoing the maker–master issue with the Replicants, adding simmering tensions. Sydney Chandler’s Wendy continues to intrigue with her alien connection, though her thread here drifts into functional, plodding setup with meandering interactions with Alex Lawther’s Hermit. Toodles gets more to do with Kirsh and name changes; however, Smee and Curly are underused throughout.

The highlight comes from Babou Ceesay’s Morrow manipulating Adarsh Gourav’s Slightly/Arrush, coercing him into betrayal and, in their second exchange, threats of loss. It’s a raw, gripping exchange. Later, Slightly’s tension with Timothy Olyphant’s Kirsh deepens the unease. Olyphant is outstanding as ever, his composed presence laced with menace. Adrian Edmondson also impresses as Atom Eins, hinting at corporate control that recalls RoboCop’s OCP—a subtle but powerful thread about ownership of bodies and lives. Eins’ manipulation of Hermit mirrors Morrow’s with Slightly, and in turn Samuel Blenkin’s Boy Kavalair (his name an obvious Android (1982) twist yet to come, perhaps?) influences Wendy.

Technically, the episode impresses with its set design, effects, and creature work. The sheep experiment and the chestburster birth are chilling and well realised, keeping the horror tangible. However, the fades and overlapping transitions are overused, becoming a heavy-handed stylistic bugbear that hampers the show. The Lost Boys/Peter Pan framing, meanwhile, wears thin, and the pop-rock track over the end credits is jarringly on the nose.

“Observation” is filled with ideas, strong performances, and unsettling imagery. But despite its strengths, it often feels stretched away from the Alien core, as though the show wants to be about everything except the creatures themselves. The result is ambitious and intelligent, yet uneven—a thoughtful hour that leaves you wondering if a more focused Alien story might have been the stronger path.
