Supergirl (2026) has become one of the most polarized entries in James Gunn’s new DCU— praised for Milly Alcock’s performance and emotional depth, but criticized for uneven direction, a weak villain and a “grimy punk rock” tone that doesn’t fully resonate.

A Fresh, Flawed Take. Craig Gillespie’s Supergirl tries to give Kara Zor‑El, Superman’s cousin, a different identity away from the bright optimism of DC heroes. Instead, the movie takes an even darker, grittier tone and portrays Kara as a sardonic, jaded wanderer in grief and anger. And while that is in stark contrast to the optimistic Superman reboot, it’s also at odds with the audience in the film wanting a more uplifting superhero story.
Milly Alcock’s Performance
Australian actress Milly Alcock shines as Kara, bringing both vulnerability and rebellious energy to the role. Critics agree she is the film’s strongest asset, embodying a character torn between her Kryptonian heritage and her desire to escape pain through reckless choices. Alcock’s portrayal makes Kara relatable, even when the script paints her as abrasive or self‑destructive. Her chemistry with supporting characters, including her loyal dog Krypto and the orphan Ruthye, adds emotional weight to the story.
Story and Themes
The story takes Kara on a cosmic journey and she is in the crossroads of grief and loneliness and moral weight. A flashback sequence shows her tragic past and makes her bitter in real loss. The main conflict comes when she’s up against Krem of the Yellow Hills, played by Matthias Schoenaerts, an intergalactic raider who is so far from the movie’s ambition. It is also the villain's design that’s impressive but critics say he’s not very intelligent and not charismatic and that in the end the stakes are low.
Critical Reception
Reception for the movie has been mixed to negative. On Rotten Tomatoes it is at about 56%, less than Superman’s 83%. IndieWire and USA Today praised its smaller‑scale adventure and emotional core and Variety called it “super‑horrendous” with a flat script. Metacritic gives it a 50/100 score with an average to poor response.
Box Office Buzz
Supergirl, despite all the exposure, is off to a poor start at the box office. The box office analysts expect to do a domestic opening of ₹415–₹455 crore ($50–55 million), which is far from Superman’s $125 million debut. That’s a doubt in what direction the film will go, in the highly competitive superhero industry.
Supergirl is a bold but uneven addition to the DCU. Its gritty tone and emotional exploration of Kara Zor‑El’s struggles is a refreshing departure from the usual superhero fare but weak writing and a weak villain keep it from going off the rails. Milly Alcock has a good performance and the film has heart, but whether viewers will embrace this dark side of Supergirl is up for debate.
