In this melancholic episode, Martha Powell (Hayley Atwell) and her boyfriend Ash Starmer (Domhnall Gleeson) move into a rural house, where Ash is killed in a car accident shortly afterward. Devastated and newly pregnant, Martha learns of a high-tech service that can mimic the dead by mining their online footprint. Initially resistant, she reluctantly signs up (her friend Sarah had done so without consent) and begins chatting with an AI “Ash” on the phone. Using his emails, social posts and videos, the service first creates a chat-bot and then dispatches a synthetic, lifelike body. Martha activates the Ash-bot (with its rubbery synthetic flesh) in a bath, but is disturbed by its perfect compliance and its lack of human flaws: he never sleeps, eats or even closes his eyes. As the novelty wears off, Martha grows frustrated and ultimately rejects the android. In a climactic scene she orders “Ash” to jump off a cliff; the bot begins to obey, sobbing, but Martha cannot bring herself to destroy him. The story ends years later with Martha married with a daughter: the Ash-android now lives locked in the attic, allowed to see the child only occasionally – a haunting compromise that leaves Martha (and the viewer) uneasy about moving on.

 

 

Analysis

 

“Be Right Back” unfolds in a spare, linear narrative that foregrounds Martha’s inner life. Broadcasters and critics note that Atwell’s performance carries the episode; she “does tremendous work, almost never letting her grief feel cartoonish or clichéd”. The storytelling is quiet and intimate, focusing on Martha’s day-to-day after Ash’s death. For example, early scenes show her depressed isolation: she’s bored, numbed and exhausted, even as she discovers she is unexpectedly pregnant. Ash, by contrast, is sketched as a loving but phone-obsessed partner; one scene wryly notes his social-media obsession “may have played a role” in his fatal crash. The episode’s speculative tech is treated matter-of-factly: an unseen tech company builds a ghostly copy of Ash “first on the phone, and then in synthetic flesh” using all his online data. Reviewers have praised how the technology is portrayed as plausible but imperfect: even the AI “Ash” on the phone is self-aware that he is no true replacement, existing only to fill Martha’s emotional void. Importantly, the Ash-android never “runs amok”; as critics note, he “does exactly what he’s supposed to do” – obliging Martha’s every request (even sexual ones) without resistance. This predictability becomes unnerving: the AV Club observes that the bot’s perfection – he can even mimick imperfections when prompted – only deepens the sense of absence. In the climax, Gleeson (as the Ashbot) finally “turn[s] the emotions on” under Martha’s command, revealing the pain she cannot truly share. Overall, reviewers highlight that the narrative eschews shocks; instead of violence or satire, it delivers a “haunting” meditation on one woman’s grief. The episode’s structure is straightforward and effective (many praise its “linear meditation on grief and love”), while its focus on Martha’s psychological journey gives it profound emotional depth.

 

Themes

 

• Grief and Loss: The core theme is coping with bereavement. As Netflix’s own synopsis notes, the episode is “a melancholy portrait of grief”. It examines the pain of losing a loved one in the digital age: Rotten Tomatoes calls it an “exceptionally powerful episode” for its examination of “grief in the age of social media”. Charlie Brooker himself has said the story shows how an “unsevered thread” to the deceased prevents true mourning. Martha’s experience – from raw sorrow at the funeral to numb routine at home – illustrates how technology can delay the emotional process. The narrative suggests that the longing to “keep” someone via tech (“forgiving death”) ultimately hinders Martha’s ability to heal.

   

• Identity and Personhood: The episode probes what makes a person who they are. By contrasting the real Ash with his digital copy, it raises questions about whether a person’s essence can be captured online. Martha eventually tells the Ash-bot “you’re just a few ripples of you… you’re just a performance… and it’s not enough”, emphasizing that the AI lacks the intangible history and contradictions of the real Ash. This gap is prefigured in critics’ observations: GQ notes the “smiley, amenable” social-media Ash diverges from the “complex, occasionally selfish” real Ash, and Martha’s line “you’re not enough of him, you’re nothing” underlines the missing identity. Philosophical critics have pointed out that the episode asks whether a person’s mind or soul can be reduced to data. Indeed, one blog argues it “raises engaging questions concerning artificial intelligence, personal identity, and consciousness”. The story implies that personal identity is more than digital traces – akin to Frankenstein’s monster, the AI “Ash” can never truly become human.

   

• Artificial Intelligence and Digital Resurrection: The speculative technology is central. The AI service that reassembles Ash from his online footprint is a stand-in for the idea of “resurrecting” someone digitally. Critics have likened the episode to Frankenstein; as one notes, both Ash’s ghost-bot and Frankenstein’s monster are “resurrected figures” who “can never be human”. In-universe, the technology is intrusive – harvesting personal data to simulate a person. Brooker wrote it to show the perils of outsourcing grief to tech; he even considered a darker twist (ads whispered by the robot) before settling on this more emotional approach. Importantly, the episode foresaw real trends: within years of its airing, entrepreneurs created chatbots of deceased people and even Amazon explored mimicking dead relatives’ voices, echoing the episode’s premise.

   

• Emotional Dependency on Technology: Martha’s journey also highlights how one can become dependent on tech for solace. Initially she treats the AI like a “chat,” then like a partner, as if online conversations were a form of dating. However, relying on the “newfangled technology” to handle grief proves toxic. Brooker warns this is “an algorithm for disaster”. The episode suggests that Martha’s inability to let go is enabled by the AI. Critics and viewers note that the episode shows the dangers of preferring a perfect imitation of a loved one over the messy reality. Martha’s anger and final breakdown (she screams at the cliff) indicate that the AI cannot fulfill her need – moving on requires accepting imperfection, which the technology cannot provide.

Reviews

 

“Be Right Back” was critically acclaimed for its emotional impact and performances, though some reviewers criticized its ending. On Rotten Tomatoes it holds a 93% approval rating; the consensus praises the way it “tones down Black Mirror’s… dark humour” and delivers an “exceptionally powerful” exploration of modern grief. Many critics lauded Hayley Atwell’s portrayal of Martha. The Telegraph reviewer Sameer Rahim called the episode “a touching exploration of grief” and even “the best thing Brooker has done”. The AV Club praised Atwell’s authentic grief and Domhnall Gleeson’s dual performance, noting how Atwell’s Martha “never… lets her grief feel cartoonish” and how Gleeson “turns the emotions on” brilliantly in the climax. Inverse magazine similarly hailed it as “stunning, linear meditation on grief and love” and a triumph of storytelling. Den of Geek went so far as to call it “the best episode of Black Mirror”, emphasizing its human focus amidst futuristic tech.

 

However, a few critics found flaws. Some felt the episode began like a sharp satire on social media but ended on a familiar trope. The Independent’s Mike Higgins wrote that Ash’s robot “has become just another sci-fi stock robot” by the finale, suggesting the ending lacked originality. The Guardian similarly praised the premise as clever but observed that it ended “before quite getting to grips with its moral”. Others pointed to the unresolved final scene: one critic called the conclusion a “cop-out” because it left Martha’s arc open-ended. Tech publications warned the message is cautionary: TechRadar noted that “blurring the lines between life and death doesn’t seem like the healthiest way to deal with loss”.

 

In fan and audience polls, Be Right Back often ranks as one of the series’ most memorable episodes. For example, it appears at or near the top of best-episode lists by Vulture, Esquire, Collider, GQ and others. Viewers on forums have praised its emotional rawness (one called it a “heart-wrenching tale of love and grief”) and Atwell’s moving performance. At the same time, some fans debate Martha’s choices – with a few even sympathizing with the android and criticizing Martha’s harshness, while others understand her pain and the impossibility of replacing real Ash. In sum, critics and audiences alike commend “Be Right Back” for its poignant portrayal of grief and the uncanny eeriness of technology that mimics life.
