Supergirl review reactions landed mixed ahead of the June 26 theatrical release, but Millie Alcock drew repeated praise in the early social posts. The first read is split: some critics liked the performances and tone, while others said the film was held back by its adaptation choices.
Millie Alcock and Jason Momoa
Chris Killian described the film as "if you threw [Guardians of the Galaxy], True Grit, and Mad Max into a DC blender, you’d get Supergirl — a grimy, funny, yet surprisingly somber space adventure." He also said Alcock was especially strong "especially when we get into Kara’s tragic backstory," while Jason Momoa looked to be having "the fraggin’ time of his life" as Lobo and David Corenswet was "peak casting" as Superman.
Erik Davis pushed the comparison further, calling out "the underdog rock n’ roll attitude of Guardians of the Galaxy" and "grimy ruthlessness." He said Alcock "brings a sort of aloofness and melancholy to the role that helps create emotional depth," and added that Momoa’s Lobo is used "just enough that you’re satisfied but also want to see more."
Tessa Smith and John Nguyen
Not every first reaction landed in the same lane. Tessa Smith called the film a "mixed bag" and wrote, "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." John Nguyen was blunter, saying the movie "felt bland" and that he left wishing Supergirl had been given stronger material to show what she can really do.
The split gives DC Studios an early signal before June 26: Alcock and Momoa are landing, but the adaptation choices are drawing the pushback. That matters because early reactions are shaping the film's first public frame before audiences see whether the performances can outweigh the criticism.
Germain Lussier and Fay Watson
Germain Lussier called Supergirl "highly enjoyable" and said it "doesn’t have the resonance of Superman," while also describing it as "a perfect companion and follow-up" with "better characters and more complex relationships." Fay Watson went even further, saying it "is the film I wish I’d had as a teenager who loved superhero movies" and that "Milly Alcock is perfect, bringing humour, heart, and incredible drunk acting."
Fico Cangiano called it a "solid follow-up to last summer’s Superman," adding that it is "more serious and emotionally heavier in tone" and "evokes Guardians of the Galaxy, with a dash of Mad Max: Fury Road and a bit of Thor: The Dark World." That mix suggests a film built to sell on character and texture first, which gives Supergirl a narrower but clearer lane when it opens in theaters on June 26.
