Benjamin S.’s review published on Letterboxd:
One of Her’s most endearing moments occurs after Twombly and Samantha’s first sexual encounter, when he awkwardly tells his OS that he isn’t interested in a serious relationship. It’s strange to see a morning after scene play out between a man and his computer, and yet that strangeness is absent from the dialogue as Johannson responds with the same charming annoyance and veiled attraction she’d provide in any romantic comedy. On the surface Samantha is defined by her nonphysical nature, but the warmth of Johannson’s performance shows the character’s emotions are not constrained by the lack of a body, that she feels with as much range and depth as any person. Rather than asking if computer programs could ever feel love, as other sci-fi films have, love is not merely possible but inevitable for Samantha. In Her, love is a fundamental part of intelligent life, and so anyone worthy of being called alive, whether human or artificial, naturally must be able to love.
At the same time, Her envisions an emotionally barren future where media technology isolates people from each other, eroding the personal connections they need to thrive. Twombly embodies that isolation as he shuffles from work to home with his eyes glued to one high-tech device or another, engaging others in only the most superficial ways. However, Phoenix’s awkward, self-enclosing performance also suggests someone not just glued to technology but also afraid of emotions, even as his sensitive letters hint at a deeply empathetic soul. Like Samantha, Twombly has a natural ability to love, but unlike his newborn OS he is burdened by past romantic failures and the fear of seeing them repeated, which discourages him from pursuing love at all. That fear pushes Twombly into a stupefying routine of media consumption that keeps other people, and the emotional risks attached to them, safely at bay. Whereas Samantha’s urge to love gives her life, Twombly’s reluctance to love leads him to numbly, thoughtlessly live out his days in front of machines, depriving him of a real life.
Given Twombly’s attachment to machines, it’s fitting that the person who finally reaches him is herself part of a machine. The chemistry between the characters is palpable despite Samantha’s invisibility, not solely because of Johannson’s strong voice work but also because of Phoenix’s total commitment to the conceit. In one scene Twombly shuts his eyes and lets Samantha guide him through a busy carnival, and as he follows her voice he moves so eagerly and joyfully that she could be leading him by the hand. Conversely, when Samantha disappears at various points in the film, Twombly’s solitude exceeds that of a man simply standing by himself. In Phoenix’s face we see a wordless grief through which Samantha’s absence is apparent, and through that sense of absence the invisible character takes shape.
Twombly is shaped by the relationship too as he ends his solitude and begins to let other people connect with him again. By the end, Twombly has realized that the ability to form those connections is itself a marvelous thing, regardless of whether or not they end in heartbreak. Samantha herself is not a perfect mate and Twombly’s relationship with her never seems sustainable, but the film treasures their bond no matter how absurd and fleeting it may be. In a world where people can rely on technology to smooth out the complications in their lives, Her argues that something as complicated and ephemeral as love has a place in our lives too, that love is in fact still what makes life worth living.
