The movie, which continues James Gunn’s DC Universe after last summer’s Superman, stars Alcock (House of the Dragon) as Kara Zor-El, who’s on a mission to save her superpup Krypto from dying after he’s poisoned by an enemy.

Ahead of Supergirl's release in cinemas later this month, several critics have posted their reactions to an early screening on social media.

These are largely positive, with some critics comparing the film to Mad Max. Others, however, note it isn’t quite on par with last summer’s Superman.

“It isn’t a classic but it’s fun and hits most of the targets it aims for,” wrote journalist Simon Thompson. "Milly Alcock is great as the titular heroine and Momoa’s Lobo is a blast. Other big wins are the action, humor and when it leans into physical production."

Journalist Mike Ryan said that the film "looks and plays more like a ‘Mad Max’ movie, with dirty worlds, gross villains and a self destructive hero".

Meanwhile, Germain Lussier of Gizmodo wrote: "Supergirl is highly enjoyable. It doesn’t quite have the resonance of Superman, but it acts as both a perfect companion and follow-up to that movie with better characters and more complex relationships. It’s also incredibly emotional, which makes the action hit even harder."

And critic Tessa Smith shared: "Unfortunately Supergirl is a mixed bag for me. As a fan of the comic, I was (perhaps) overly excited for the film adaptation. While Jason Momoa's Lobo & Milly Alcock shine, some adaptation choices and a bland villain keep it from greatness. It's, simply put, just fine."

Supergirl is based on the comic series Supergirl: Woman of Tomorrow by Tom King and helmed by Craig Gillespie.
