Milly Alcock soars as Supergirl in a dark, uneven narrative that’s wildly entertaining but likely to divide fans of the comic book source material. Themes of grief, vengeance, and finding your true purpose are explored in an action-packed chase across the galaxy that the film itself campily describes as an interstellar “pub crawl.” That vacillation between drunken party humor and surprisingly vicious savagery lies at the heart of Supergirl’s biggest problem. It’s telling a deadly serious story while being overly whimsical with the anti-hero Lobo (Jason Momoa) and aw-shucks good-guy Superman (David Corenswet) sprinkled throughout.
