Representing less a defiant step forward into a new era of the DC Cinematic Universe than a retread of the by-the-books superhero fare of the past decade, director Craig Gillespie’s “Supergirl” flies along well enough but shoots out of memory soon afterwards.

We first meet Kara Zor-El a.k.a. Supergirl (Milly Alcock) as she boozily zips from planet to wacky planet in celebration of her 23rd birthday. With the lovably destructive CGI dog Krypto in tow, Kara has a laissez-faire attitude toward life, clearly preferring to party than confront the trauma of her tragic backstory. She also avoids Earth at all costs — much to the frustration of Superman (David Corenswet), who’s increasingly worried she won’t ever “find her people.” 

Things take a turn for the explosive when Kara encounters Ruthye (Eve Ridley), a young woman seeking revenge after her family was murdered by Brigand leader Krem of the Yellow Hills (Matthias Schoenaerts). Kara saves Rutheye from a squelchy brute straight out of the “Star Wars” Mos Eisley Cantina, but refuses to help her track down the bloodthirsty trafficker.

Krem has other plans, though, when he hijacks Kara’s ship and shoots poor Krypto with a poisonous dart that gives the pup only three days to live. This motivates Kara to track him down to retrieve the antidote, and reluctantly take on Ruthye as her novice (but underestimated) sidekick. 

As the pair rush to track down Krem, they develop a friendship (wow!), each teaching the other about the power of community and reckoning with grief. They deal with bouts of punchtastic action and formulaic villainy along the way. Plus, an unhinged, motorcycle-riding Jason Momoa appears as the intergalactic bounty hunter Lobo!

If one expects  “Supergirl” to break the mold of what’s come before, get ready for disappointment. Gillespie’s film starts out strongly enough, decidedly wackier and more committed to showing a colorful galaxy than other recent outings, as well as establishing Alcock as a perfect fit for the role of Kara. 

Alcock’s dry comedic timing is spot-on, with Ana Nogueira’s screenplay leaning into her cynicism and dry wit in a way that never becomes tiresome, building a character far less “polished” than Corenswet’s Superman, and one that’s all the more enjoyable to watch for it. 

Sadly, before long, the film slides back into the template we’ve seen time and time again, awkwardly sandwiching humor between “sobering” backstory that’s clunkily assembled and largely bereft of earned poignancy.

Gillespie ultimately trades the energetic personality of the opening for something far drearier and, crucially, blander, as the PG-13, green-screened violence kicks into high gear and we realize that, no, none of the heroes are truly in danger amid the swirl of crowd-pleasing clichés. 

Kara and Ruthye’s bond is believable, to an extent. Kara’s bond with Ruthye and seeing her hunger for revenge leads her to reflect on her own  past, gradually understanding herself and her deep-seated anger at the world as she eventually transforms into the “Supergirl” that she’s destined to become.

This is a passable arc — it’s just that Gillespie’s storytelling lets Kara down, awkwardly jumping into flashbacks that are rushed through without letting us sit and feel the sadness and disorientation that Kara experiences. Gillespie and Nogueira opt for a barebones outline instead of fleshing out her past in more detail, perhaps assuming that viewers already get the gist from the comics.

Fortunately, “Supergirl” moves along at a brisk enough clip. We’ve got the monstrous, albeit extremely one-note baddie Krem, the goofily out-there Lobo (Momoa understands the assignment), and plenty of quip-filled set-pieces complete with peppy needle drops. 

It’s just that, with such an excellent actor as Alcock in the starring role, doesn’t she deserve something more substantial to work with from a narrative standpoint? She’s even let down from an action perspective.

Rob Hardy’s cinematography is often eye-catching and keeps the fighting coherent, but these sequences are unwilling to fully let Kara off the chain, too often kneecapping her powers just when she starts using them. They fall into a frustrating stop-start pattern that persists all the way through the final battle.

“Supergirl” is still an entertaining enough watch despite its numerous issues — the template is functional, after all, although the pointed social commentary of James Gunn’s “Superman” is definitely missed here.

There’s nothing offensively off-putting about Kara’s debut. It’s just an affirmation that, at their core, these films might never truly change.

“Supergirl” is a 2026 sci-fi action-adventure directed by Craig Gillespie and starring Milly Alcock, Matthias Schoenaerts, Eve Ridley, David Corenswet, Jason Momoa, Emily Beecham and David Krumholtz. It’s runtime is 1 hour, 47 minutes, and is rated PG-13 for sequences of strong violence, action, language, and smoking. It opens in theatres June 26. Alex’s Grade: C+
