Initial reactions to the upcoming film 'Supergirl' have emerged from film critics on social media, ahead of its June 26 theatrical release.

The Craig Gillespie-directed movie features Milly Alcock in the titular role, following her cameo in last summer's 'Superman' film.

Jason Momoa takes on the character of Lobo, while David Corenswet reprises his role as Superman.

Overall sentiment appears to be mixed, with some critics offering high praise for specific performances and the film's tone, while others found aspects to be less impactful.

This early feedback provides insight into how the film might be received by a broader audience.

Chris Killian of Comicbook.com described 'Supergirl' as a blend of 'Guardians of the Galaxy,' 'True Grit,' and 'Mad Max,' characterizing it as a "grimy, funny, yet surprisingly somber space adventure." Killian specifically commended Alcock's portrayal, particularly in scenes exploring Kara's tragic backstory, and noted that Jason Momoa seemed to be thoroughly enjoying his role as Lobo.

He also highlighted the film's practical effects and lauded David Corenswet as Superman, calling it "peak casting" and stating that Corenswet's presence on screen consistently brings a smile.

Conversely, movie critic Tessa Smith shared a "mixed bag" reaction, expressing that while Jason Momoa's Lobo and Milly Alcock "shine," certain adaptation choices and a "bland villain" prevented the film from achieving greatness, ultimately deeming it "just fine." Erik Davis echoed comparisons to 'Guardians of the Galaxy' and 'Mad Max,' describing the film as having an "underdog rock n' roll attitude" and "grimy ruthlessness." Davis praised Alcock for bringing "aloofness and melancholy" to the role, creating emotional depth, and felt Momoa's Lobo was used effectively, leaving audiences wanting more.

He also agreed that Corenswet was the "perfect choice" for Superman.

John Nguyen of Nerd Reactor, however, found 'Supergirl' to be "bland," wishing the character had been given stronger material.

Germain Lussier commented that while the film is "highly enjoyable," it lacks the "resonance of Superman," yet serves as a strong companion with better characters and more complex relationships.

Lussier also noted its emotional depth, which he felt enhanced the action.

Fay Watson of Total Film praised Alcock's performance, citing her humor, heart, and "incredible drunk acting," and appreciated Craig Gillespie's vision, describing it as having "Mad Max vibes" but ultimately being unique.

Fico Cangiano called 'Supergirl' a "solid follow-up" to 'Superman,' highlighting its more serious and emotionally heavier tone, and comparing it to an intergalactic road trip reminiscent of 'Guardians of the Galaxy,' 'Mad Max: Fury Road,' and 'Thor: The Dark World.'
