Supergirl (2026) Review: A Gritty, Divisive Cosmic Road Trip

This Supergirl review starts with a simple point: Craig Gillespie's 2026 superhero film is a rougher, moodier take on Kara Zor-El than most people expect. It is also a divided one, with audiences split between those who love its attitude and those who find it unfocused. Here is where it lands.

Supergirl Review: The Story So Far (No Spoilers)

The Supergirl plot follows Kara Zor-El after a ruthless adversary hits too close to home. Instead of staying put, she reluctantly teams up with an unlikely companion and heads out on an interstellar trip driven by vengeance and a hunger for justice.

The tagline, "Truth. Justice. Whatever.", sets the tone well. This Kara is not a bright, flag-waving symbol. She is guarded, weary and carrying real survivor's guilt, and the script by Ana Nogueira builds the journey around that wound.

It is a space-bound action-adventure at heart, and it moves quickly at 108 minutes. If you want more of the genre, browse our action movie reviews and adventure movie reviews.

What Works in Supergirl

A grittier, more personal hero

The best thing about the film is its emotional starting point. Several viewers praise the quieter moments, where Kara's grief and isolation take centre stage. That gives the superhero spectacle a human core that many recent blockbusters lack.

Texture and scale

Gillespie leans into a lived-in, dusty cosmos of dive bars and rough outposts rather than a clean, polished sci-fi world. Audience reactions describe the look as gritty and visually striking. The film feels like a road movie that happens to cross the stars.

A fresh tone

The attitude is a change from the usual earnest approach. It is looser, scrappier and sometimes funny, and it gives the character room to be flawed.

Supergirl Cast and Performances

The Supergirl cast is led by Milly Alcock, and most responses single her out as the film's anchor. She plays Kara with a mix of raw vulnerability and fierce strength, though a few critics found the moody, drifting version of the hero less compelling.

Jason Momoa plays Lobo and is often called a scene-stealer. His swagger brings energy whenever he turns up.

Eve Ridley plays Ruthye, the companion at the centre of the journey. Her performance gets a more mixed reception, with some viewers feeling the emotional connection is inconsistent. Matthias Schoenaerts plays Krem, and David Krumholtz and Emily Beecham appear as Zor-El and Alura In-Ze.

Where Supergirl Stumbles

The film's biggest problems are familiar ones. Several reviewers describe the villain as bland, and the story as thin or drifting from one generic fight to the next. When the central threat lacks weight, the revenge plot loses urgency.

The tone is also uneven. Some viewers complain about mood-breaking needle drops, and others say the film feels designed by committee, unsure who its audience is.

• A forgettable antagonist

• An emotional anchor that doesn't always land

• Action that can feel generic

The box office has been modest against a reported $170 million budget, which suggests the mixed word of mouth has had an effect.

Is Supergirl Worth Watching?

Yes, if you are curious about a grittier superhero story and are willing to forgive a loose script. The audience score of 6.6 out of 10 reflects a film that has real fans and real detractors.

Alcock's performance and the film's personal tone are enough to make it interesting. The weak villain and uneven style keep it from being essential. If you are asking is Supergirl worth watching, it is a solid rental or matinee rather than a must-see event.
