Not a Sidekick, But a Client
First, let's get one thing straight: In *Supergirl: Woman of Tomorrow*, the comic book source material for the upcoming film, Ruthye is not a sidekick. She is the story’s narrator and its driving force. She’s a young alien from a technologically primitive
planet whose father is murdered by a ruthless villain. Possessing a fierce, almost medieval sense of justice, she sets out not just to find the killer, but to execute him. To do so, she needs help, so she seeks out a hero for hire. The hero she finds is not the bright, smiling champion she expected. Instead, she finds Kara Zor-El, celebrating her 21st birthday by getting drunk alone at an intergalactic dive bar. Ruthye is the client. Kara is the broken instrument of vengeance she hires. This dynamic completely upends the traditional hero-sidekick relationship, framing their entire journey as a grim business transaction.
The Supergirl We've Never Seen
The Kara of *Woman of Tomorrow* is a revelation. For decades, Supergirl has been defined by her relationship to Superman—his younger, more optimistic cousin; the other survivor of Krypton. This story shatters that. Writer Tom King brilliantly reframes her experience: Superman was a baby who doesn't remember Krypton. Kara was a teenager. She remembers her home, her friends, her parents. She watched her world die. She arrived on Earth a traumatized refugee, and for years, she has bottled that cosmic-level trauma and rage beneath a veneer of heroism. This story finds her on the verge of breaking. She’s cynical, tired, and filled with a fury she can barely contain. She’s not just powerful; she’s dangerous. This isn’t a story about a girl trying to live up to her cousin’s legacy; it’s about a woman wrestling with a pain that is uniquely and profoundly her own.
The Moral Mirror
This is where the movie’s true challenge lies. The entire emotional core of the story rests on how Ruthye’s simple, righteous quest for vengeance holds up a mirror to Kara’s far more complex and destructive anger. Ruthye wants to kill one man for one crime. Her fury is focused and, in the context of her world, just. Kara’s fury, however, is boundless. It’s the ambient radiation of a dead planet, a lifetime of loss she has never been allowed to properly mourn. When she looks at Ruthye, she sees a miniature version of her own rage. But in Ruthye’s quest, Kara is forced to confront what justice and vengeance actually mean. Is killing the man who wronged you a heroic act? Is it a solution? Ruthye’s journey becomes a test for Kara’s soul. By helping this determined child, Kara is forced to examine the darkness within herself and decide whether she will be consumed by it or finally rise above it. This isn’t something that can be explained in a line of dialogue; it has to be felt in the quiet moments between them.
Why It’s So Hard for a Movie
Blockbuster superhero films are built for spectacle. They excel at showing buildings topple and aliens getting punched. They are notoriously less skilled at portraying profound, internal character struggles. The hardest job for director Craig Gillespie and actress Milly Alcock won’t be choreographing the fight scenes or designing alien worlds. It will be capturing the subtle, often silent, dynamic between a disillusioned demigod and a stubborn child. It’s a relationship built on shared trauma, unspoken understanding, and the slow, difficult process of healing. A movie needs to translate this through performance, subtext, and careful pacing—all elements that can be easily sacrificed for the sake of a bigger action sequence. If the film prioritizes the explosions over the emotional fallout, it will miss the entire point of what makes *Woman of Tomorrow* a modern classic.
