This Supergirl review contains spoilers for the new DCU film starring Milly Alcock as Kara Zor-El.

There are bad movies that make you angry. There are messy movies that make you want to argue for them. And then there are movies like Supergirl, which commit a quieter, more annoying sin: they are just fine enough to vanish while you are still walking back to the car.

That was my immediate reaction after seeing the new DCU film. Not rage. Not devastation. Not even real disappointment, exactly. Just a kind of shrugging emptiness. Mary put it best the second we left the theater: “This could have been an email.”

And honestly? That might be the whole review.

That is the real problem with Supergirl. Not that it is terrible. Terrible movies at least leave a mark. This is a forgettable DCU movie with just enough talent, just enough premise, and just enough franchise importance to make its emptiness feel more frustrating. It has the shape of a meaningful Kara Zor-El story, but not the force of one.

Supergirl is not a catastrophic failure. It is not an unwatchable disaster. It has pieces that should work. Milly Alcock has the right kind of bruised, sideways energy for Kara. The premise has weight. The movie clearly wants to give us a Supergirl who is not just “girl Superman,” but someone sharper, sadder, more damaged, and more cosmically unmoored.

All of that is good in theory. The problem is that the movie itself often feels like a franchise memo dressed up as a feature film.

Watch The Supergirl Trailer

Before getting into the larger problem, here is the official trailer for Supergirl, which sells a bigger, stranger, more emotionally charged movie than the one I felt like we actually got.

Supergirl Review: A Forgettable DCU Movie

The strangest thing about Supergirl is that it feels like it was made by the world’s biggest James Gunn fanboy. Not James Gunn himself. Not someone channeling the emotional machinery of Gunn’s best work. But someone who watched Guardians Of The Galaxy, The Suicide Squad, and Superman, circled the surface-level ingredients, and decided that was the recipe.

Oddball supporting characters? Check. Cosmic weirdness? Check. A wounded hero using attitude as armor? Check. A little irreverence? Check. A strange creature companion? Check. A story about grief, found purpose, reluctant heroism, and moral messiness? Check.

But Gunn’s best stuff does not work because it is quirky. It works because the quirk is camouflage. The joke is usually hiding a wound. The creature is usually not just cute, but emotionally load-bearing. The punk-rock attitude is not there to say, “Look how fun this is.” It is there to create friction between pain and performance.

Supergirl understands the costume. I am not sure it understands the body underneath it.

That is why the movie feels so weirdly secondhand. It keeps reaching for that Gunn-adjacent mix of cosmic, sad, funny, violent, strange, and heartfelt, but it rarely earns the emotional turn that would make any of it stick. It is not enough to put Kara in space, give her an edge, hand her some trauma, and tell us she is different from Clark. The movie has to make that trauma move.

It has to dramatize the difference between who Kara is when the story starts and who she becomes by the end. Instead, it mostly delivers the information.

Kara is damaged. Kara is different from Superman. Kara is angry. Kara has seen more. Kara is capable of hope, but hope does not come naturally to her.

Great. That is the email. Where is the movie?

Milly Alcock Is Not The Problem

To be clear, Milly Alcock is not the issue here. If anything, she is one of the reasons the movie remains watchable. She has the right presence for this version of Kara: guarded, funny, wounded, impatient, and clearly carrying a history she does not want to explain to everyone in the room.

There are moments where Alcock suggests a much more interesting interior life than the movie knows how to fully support. You can see the outline of a character who has survived an impossible loss and developed a personality around not having to feel it all the time. That is a good Supergirl angle. That is a real distinction from Superman. Clark was raised by love. Kara was raised by catastrophe.

That should matter in every scene.

But too often, Supergirl treats that distinction like a character note instead of a dramatic engine. Kara’s pain is present, but it does not always shape the movie around her. Her grief is named more than it is transformed. Her moral difference from Clark is suggested more than it is tested.

And that is frustrating, because the bones are there. Alcock is there. The contrast with Superman is there. The revenge framework is there. The opportunity to make something visually wild and emotionally jagged is right there.

The movie just keeps choosing the easier version of itself.

Why Does Supergirl Look So Bad?

The most confusing part of Supergirl is how flat it looks. Rob Hardy shot this movie, and Hardy also shot Ex Machina and Annihilation, two films with clear, memorable visual identities. Ex Machina made glass, concrete, and artificial intelligence feel seductive and dangerous. Annihilation made nature feel beautiful, diseased, and apocalyptic.

That is why Supergirl is so baffling. This should be a cosmic road movie with strange worlds, emotional contrast, and a visual language that tells us something about Kara’s grief. Instead, too much of the film feels muddy, samey, and strangely anonymous.

It is not ugly in a bold, expressive way. That can be great. I love ugly when ugly means something. I love grime when grime has a point. I love a superhero movie that refuses to look like plastic.

But this is not that.

This is ugly in the way a movie looks when every location feels pulled through the same desaturated franchise filter. For a movie about an interstellar journey, there is very little sense of visual discovery. Space should feel dangerous, alluring, strange, ancient, funny, sacred, disgusting, or impossible. Ideally, all of the above at different points.

Instead, too much of it feels like the same gray-brown mood board being dragged from location to location.

That is fatal for a Supergirl movie because Kara’s whole deal in this version should be contrast. She is not Clark. She did not get the Kansas moral blanket. She carries Krypton differently. She carries loss differently. She should move through worlds that challenge, expose, and sharpen that difference.

The visual language should be doing half the storytelling. Instead, it mostly just sits there.

This Supergirl Movie Feels Abbreviated, Not Lean

I do not think every superhero movie needs to be two and a half hours long. Some stories should be tight. Some movies are better when they move quickly. There is nothing inherently noble about bloat.

But there is a difference between lean and abbreviated.

And boy, oh boy, does Supergirl feel abbreviated.

It feels like the movie is constantly cutting away from the stuff that would have made it personal. The stuff that would have made the grief specific. The stuff that would have made the worlds matter. The stuff that would have turned Kara from “cool damaged superhero” into an actual emotional engine.

The film moves, but it does not always build. It has incidents, but not enough emotional escalation. It has attitude, but not enough personality. It has a journey, but not enough discovery. And when a movie is built around a cosmic trip through strange worlds, that lack of discovery becomes a serious problem.

A movie like this has to make the experience necessary. Not the plot. Not the setup for the next DCU entry. Not the character placement on the franchise board. The experience.

That is the “this could have been an email” problem. The movie gives us an update. Kara is here. Kara is damaged. Kara matters. Kara will probably matter later. Fine. But as its own piece of storytelling, the film never becomes as urgent as it needs to be.

The James Gunn Shadow Is All Over Supergirl

The other fascinating layer is how much Supergirl feels like it is living in the shadow of James Gunn’s DCU voice. That is both understandable and dangerous.

Understandable because Gunn’s tone has become the first real organizing language of this new DC era. He likes wounded outsiders, strange teams, jokes that undercut pain, creatures with emotional importance, and heroes who are not cleanly heroic until they have been forced through the mess of themselves.

Dangerous because tone is not structure. Quirk is not character. Irreverence is not automatically personality. A weird creature is not automatically a relationship. Cosmic color is not automatically wonder.

Supergirl has the ingredients we associate with Gunn’s best superhero work: cosmic weirdness, a wounded outsider, offbeat humor, a creature companion, and a hero whose attitude is clearly covering pain. But ingredients are not the same thing as an emotional engine.

Gunn’s best stories work because the quirk is usually hiding a wound. The joke is not just a joke. The creature is not just a creature. The strange team or strange world is there to pressure the hero into revealing something true. Supergirl copies some of that surface language, but it rarely earns the deeper turn. It feels like someone copied Gunn’s handwriting without understanding his grammar.

That tension could have been electric. Instead, it often feels managed.

Supergirl Ending Explained: Kara’s Choice Is More Interesting Than The Movie Around It

The ending of Supergirl is built around a question that should be perfect for Kara: what does justice look like when your whole life has been shaped by loss?

That is the right question for this character. Kara should not have the same relationship to mercy, restraint, and hope that Clark does. Superman’s morality is rooted in the life he was given on Earth. Kara’s morality is haunted by the life that was taken from her on Krypton.

That makes her final choice interesting in theory. The movie wants her to stand at the edge between vengeance and justice, between proving her pain and choosing something larger than pain. That is classic superhero material, but it is also specifically Supergirl material because Kara’s trauma is not abstract. She remembers what Clark never really had to remember.

The problem is that the movie has not built enough emotional pressure around that choice for it to fully land. We understand what the ending means. We understand the moral shape of it. But understanding is not the same thing as feeling. The ending has the right idea. It just does not have enough dramatic weight behind it.

Supergirl Is Okay, And That Is The Problem

Again, I did not hate this movie. That almost makes the reaction harder to write. Hate gives you energy. Hate has shape. Hate lets you grab the thing by the throat and explain exactly where it betrayed you.

This is more slippery than that.

Supergirl is competent enough to survive the screening and forgettable enough to evaporate afterward. There are moments where you think, “Okay, there is the movie.” There are flashes where Alcock’s performance suggests a much more interesting interior life. There are ideas about vengeance, justice, grief, and moral inheritance that absolutely belong in a Kara Zor-El story.

But the film never coheres into something urgent. It never feels inevitable. It never fully convinces me that this story had to be a movie.

And that is the most damning kind of okay.

A Supergirl movie should not leave you thinking, “Well, that happened.” It should leave a bruise. It should leave a spark. It should make Kara feel like a problem the universe does not know how to solve yet.

Instead, this one mostly left me with Mary’s line echoing in my head.

This could have been an email.

And the more I sit with it, the more damning that feels.
