Last week, I found myself returning to the film, not for its science, but for the relationship at its center. Rocky reminded me of my dog, Goldie, who died three years ago, a loss that still lingers. Unlike Rocky, she was not meant to save the world. But she mattered to me just as much. The way she loved, with loyalty, trust, and a quiet innocence, felt strikingly similar.
That reaction made me wonder what it is about Grace and Rocky that resonates so widely. One answer might be Ryan Gosling, who has built a career on disarming audiences, from the Notebook to Barbie. He is, after all, in the business of melting hearts. But, Rocky is something else entirely: a faceless, rock-like creature who, against expectation, still manages to move us.
From an evolutionary perspective, we are often drawn to cute creatures, round faces, large eyes – the visual cues of babies and small animals, echoed in characters like E.T., WALL-E, or Grogu. These forms reliably trigger care, even affection.
Rocky has none of them.
This suggests that it is not Rocky’s “cuteness,” or even Grace’s relatability, that moves us most. It is something in their dynamic, something that reaches toward a more childlike part of ourselves. There is a kind of disarming purity in the way they care for one another, a way of relating that feels at once simple and rare. Most of us have known some version of it before. As children, we love without calculation, without defensiveness, without ego.
In psychological terms, this resembles secure attachment. At its simplest, secure attachment is a sense of reliability, the felt certainty that someone will be there when it matters. It is shaped less by what we say than by what we do, repeated over time, until trust becomes almost assumed.
But their relationship begins in the absence of it. When Grace first encounters Rocky’s ship, Blip-A, he assumes it is dangerous, a reaction shaped as much by instinct as by a lifetime of alien invasion stories.
That instinct is not a flaw. It is part of how we survive. At the sight of a snake, we react before we think. Many of us have mistaken a branch for a snake on the ground. Even if the risk is small, the cost of getting it wrong can be fatal. It is safer to assume danger than to pause and calculate.
The same instinct that helps us survive can quietly undermine our relationships. Have you ever assumed something about someone, only to find out you were wrong? If not, you might be unusually perceptive.
We do this more often than we realize. In everyday communication, we mistake branches for snakes, with people we have known for years, and with strangers alike. In close relationships, even a passing remark can register as criticism, setting off a familiar chain: fear, self-doubt, defensiveness. We react by protecting ourselves, rather than approaching one another with trust.
Grace, who is naturally cautious, does not arrive at trust on his own. It is Rocky who first shows openness, approaching without assuming threat, persistently reaching out, even building small models to communicate. In many ways, it is Rocky who makes it possible for Grace to feel safe enough to trust.
Trust does not mean the absence of tension. In the “roommate” scene, Rocky decides to move in with Grace without asking. He can be blunt, even dismissive, calling Grace’s workspace “boring” and “dirty.” Grace, in turn, struggles with the lack of personal space and finds Rocky bossy.
Yet these tensions do not define their relationship. Something larger is at stake, making it difficult to get stuck in small differences.
