DC’s new Supergirl movie was supposed to be a showcase for James Gunn’s rebooted universe and a star-making turn for Milly Alcock, but instead it’s become the franchise’s first big stumble — one the comic’s writer, Tom King, is now publicly unpacking. Centered on Kara Zor‑El and drawing heavily from King’s acclaimed Supergirl: Woman of Tomorrow, the film’s soft box office and polarizing reviews have turned a victory lap for DC Studios into a post‑mortem on what went wrong and what it means when a beloved comic becomes a divisive blockbuster.
Financially, Supergirl never got off the launch pad. The film opened to about $38 million in North America and roughly $68 million worldwide in its first weekend, a weak debut for a major superhero tentpole. It has since crawled to around $126 million globally, far short of its reported $170–186 million production budget and the roughly $315 million it was said to need to break even, making it a bona fide box‑office bomb for DC’s new era. The drop-off was brutal: domestic ticket sales plunged more than 75% in the second weekend as the movie quickly slid out of the top five, ceding the summer spotlight to bigger, more broadly appealing releases.
The reception from critics and audiences has been just as uneasy. On Rotten Tomatoes, Supergirl has hovered in the low‑to‑mid‑50% range, while Metacritic logged a score of 50 out of 100 — squarely “mixed or average.” CinemaScore polling landed at a B‑, a notably lukewarm grade for a splashy superhero film, with just over half of PostTrak respondents saying they would definitely recommend it to others. Coverage from major outlets has echoed that ambivalence: some reviewers call the movie bland or derivative, arguing it never fully takes flight even as it gestures toward more ambitious themes.
Yet in almost every review, Alcock herself emerges as the clear bright spot. Critics have repeatedly separated her performance from the uneven screenplay, praising the swagger and vulnerability she brings to Kara even when the story around her feels thin. Articles have described her as “alive and likable” in a role written as one‑note, crediting her for the moments when the film almost soars and for grounding the cosmic adventure with a human core. That disconnect — a charismatic new lead stranded in a structurally shaky movie — is part of why fans are so frustrated: it feels like DC got the hardest part right and then stumbled on everything surrounding her.
King’s comic provides a key lens for that frustration. Supergirl: Woman of Tomorrow, created with artist Bilquis Evely, is a character‑driven space odyssey that follows Kara on a morally complicated mission across strange worlds, mixing cosmic western vibes with introspective drama. The film borrows that basic road‑trip structure and several signature elements, but as reviews have noted, it streamlines and sandpapers much of the comic’s thornier emotional beats in favor of a more familiar origin‑story arc. In discussing the movie’s performance, King has addressed the reality that once a story leaves the page, it becomes its own thing — and that not every risk that works in comics will automatically translate into a four‑quadrant summer movie.
All of this is playing out under the microscope of Gunn’s freshly restarted DC Universe, where Superman launched to stronger reviews and box office earlier and set high expectations for every follow‑up. DC Studios leadership has publicly expressed confidence in the long‑term plan even as they acknowledge Supergirl’s numbers as a setback, signaling that Alcock’s Kara is intended to remain a pillar of the franchise despite the rocky first outing. For fans, King’s measured response and the industry’s post‑release autopsy hint at a familiar crossroads: does DC double down on what works — Alcock’s performance, the more eccentric cosmic tone of the source material — or retreat to safer, more conventional superhero formulas?
For now, Supergirl is heading to streaming after its abbreviated theatrical run, giving the film a second chance to find an audience beyond the opening‑weekend narrative. If word of mouth around Alcock and the more character‑focused moments grows, the movie may yet earn cult status even as the balance sheet stays red. Regardless, the conversation King has sparked around adaptation — how closely a film should track its comic, how much room there is for weirdness in a billion‑dollar universe — ensures that Kara Zor‑El’s latest journey will continue to shape DC’s creative choices long after the box‑office dust settles.
