The upcoming DC Universe film, "Supergirl," has received its first wave of critical reactions, with many reviewers highlighting the strong performances of its lead actors.

While the overall reception for the movie, directed by Craig Gillespie, appears to be mixed, there is a consistent thread of praise for the casting choices.

Milly Alcock, known for her role in "House of the Dragon," takes on the mantle of Kara Zor-El, Supergirl.

Critics suggest that Alcock's portrayal offers a distinct take on the character, differentiating her from David Corenswet's Superman.

Jason Momoa, who previously played Aquaman, steps into the role of the villain Lobo, a character he reportedly long desired to play.

Reviewers like BJ Colangelo from /Film described Alcock as a "fantastic Kara" and called the film an "entertaining (and sometimes depressing) take on a 'True Grit' in space." Colangelo also noted that "Jason Momoa was born to play Lobo," and praised Eve Ridley's performance as Ruthye, despite some reservations about the CGI.

Another critic, Tessa Smith, offered a more tempered view, stating that "Supergirl is a mixed bag for me." While acknowledging that "Jason Momoa's Lobo & Milly Alcock shine," Smith felt that certain adaptation choices and a "bland villain" prevented the film from reaching its full potential, ultimately calling it "just fine." The consistent positive feedback for Alcock and Momoa suggests that the casting decisions are a significant strength for the film, even as other aspects draw varied opinions.
