Supergirl 4K Blu-ray Movie Review

Lobo can't even save this.

Reviewed by Randy Miller III September 10, 2026

I may not always hit the critical mark but I'm willing to give any lambasted comic book film a fair shake, having seen and actually kinda enjoyed dog-piled DC bombs like The Flash and Shazam: Fury of the Gods. But some are worthy of the hate -- Wonder Woman 1984, Joker: Folie à Deux, and especially Black Adam immediately come to mind -- and you can now add Craig Gillespie's Supergirl to that list, as it's a painfully by-the-numbers and unlikable exercise in bloated production design attempting to hide the shortcomings of a bad script. Gunn, we have a problem.

So, what's the best way to introduce a character in her first solo film since 1984? Make her a spoiled brat, of course. Yep, Kara Zor-El AKA Supergirl (Milly Alcock) is a sarcastic and self-loathing nepo baby who spends her extended 23rd birthday by constantly drinking, sleeping in late, and bumming around with her obnoxious dog Krypto while shrugging off concerned messages from Superman back on Earth. She's made a habit of fleeing from her responsibilities at home and, as part of her extended intergalactic birthday party, is currently on the planet Holzher which is plagued by ruthless bandits called the Brigands. Their leader Krem (Matthias Schoenaerts) has just murdered the family of teenage Ruthye Marye Knoll (Eve Ridley) to steal fer father's stash of legendary hand-crafted weapons, so Ruthye begins a crusade to avenge her family's death... and during her search, she's assisted by Kara despite her current lack of powers. During a later run-in with the Brigands where Krem steals her ship, Kara's beloved Krypto is shot with a poison dart that'll kill him in three convenient days. Hoping to preempt a John Wick scenario, Kara is now on the hunt for Krem too... but she doesn't want Ruthye to come, since she'll likely kill him instead of, well, just maiming or whatever.

Of course, Ruthye tags along anyway and, as their shared search continues, it slightly expands to include a human trafficking ring as well as sporadic appearances by both Superman (David Coronswet) and Lobo (Jason Momoa), who seem to only be there for name value. But Supergirl mainly boils down to a two-pronged revenge story, and not a very good one at that: any semblance of drama or momentum is crippled by Kara's wishy-washy views about revenge, and the constant location switches and developments often include easy reasons to rob Kara of her abilities and prolong the threadbare plot. That's another thing: at a relatively modest 108 minutes (by comic book movie standards, at least), Supergirl could've helped reset a genre that regularly pushes its stories to exhaustion. Here, it's just the more familiar scenario of a short film's plot pushed to feature film length. Without even digging deeper to include the questionable casting, hit-or-miss CGI effects, cheap fan service, poorly-placed flashbacks, mediocre villain, and awful needle-drop music cues delivered at predictable moments, most first-time viewers should be able to stand several feet back and still clearly see that Supergirl is either (1) noticeably below average or (2) a total misfire that deserved box office disaster. Even with the generous handicap of lowered expectations, this one doesn't clear the bar.

I'm told that Supergirl was in fact loosely adapted from the Eisner Award-nominated Supergirl: Woman of Tomorrow, an eight-issue limited comic book series from 2021 that included exactly zero appearances from Lobo and, given its comparatively warmer reception, likely served up a much more thoughtful story and characters to match. Here, it just feels like boring old business as usual during a film that plays like the plots and ideas from several earlier genre entries were force-fed into an AI prompt, dressed up with loads of effects, and adorned with tropes we've seen in at least a half-dozen movies involving James Gunn. Supergirl deserves better than Supergirl, and so do you.

Warner Bros.' separate 4K and Blu-ray editions of Supergirl boast terrific A/V merits and several extras, so established fans will at least be happy. A Limited Edition Steelbook combo pack arrives later on October 13.

Supergirl 4K Blu-ray Movie, Video Quality 

NOTE: These screenshots are sourced from the UHD disc but downscaled to 1080p/SDR and should not be considered an accurate representation of true 4K picture quality in terms of detail, color, and brightness levels.

As expected, Warner Bros. has brought Supergirl to home video in its native 4K with energy to spare. I can't say that I'm a fan of the film's overall look but it's been preserved excellently here, as the 2160p/HDR10/Dolby Vision transfer plays extremely smoothly from start to finish with absolutely no hiccups along the way. While their appearances and palettes may differ, you can expect a high-quality presentation similar to other recent DC 4K titles such as Superman, Aquaman and the Lost Kingdom, and the aforementioned Joker: Folie à Deux, all of which earned easy 5/5 ratings for their high amount of visual precision. Disc encoding is very good as well with no signs of banding, macro blocking, or other compression-related problems along the way, and the bit rate stays consistently high as needed on this triple-layered (100GB disc). Overall, it's basically a perfect effort and that's always good news.

Supergirl 4K Blu-ray Movie, Audio Quality 

The audio is almost objectively perfect as well, boasting a very full-bodied presence and a very muscular sound stage that absolutely carries all of Supergirl's action, dialogue, and original score with ease. Low frequency effects are ample and delivered with precision, as are a countless number of crisp channel pans and other sonic surprises that arrive at key moments. While I'm again not a fan of the film's endless needle-drop music cures -- whether diegetic or not -- they likewise sound terrific as well and, as with other aspects of the presentation, nicely fill out a pitch-perfect Dolby Atmos mix that predictably makes great use of the format's strengths and available channels. Even if you're limited to the folded-down Dolby TrueHD 7.1 mix, this is a very impressive effort that earns yet another easy 5/5 rating.

Optional subtitles, including English (SDH), are offered during the main feature and all extras listed below.

Supergirl 4K Blu-ray Movie, Special Features and Extras 

This one-disc release ships in a keepcase with a matching lenticular slipcover; a Digital Copy code is tucked inside, and we also get a decently broad assortment of lightweight extras.

• Flying Off the Page (11:02) - James Gunn, writer Ana Nogueira, and others speak briefly about the main character's varied history in comics and how they approached the adaptation process.

• Girl's Best Friend (5:25) - A short featurette about the history of diamonds that takes a look at... oh, this one's actually about Krypto? Not sure they got the phrase right there.

• A Practical Legacy (11:04) - Fans get a look at several well-done practical effects used in the film.

• The DC Dream: Lobo (6:43) - An obligatory piece on one of two big-name guest stars.

Supergirl 4K Blu-ray Movie, Overall Score and Recommendation 

Craig Gillespie's Supergirl is just about as bad as you've heard, a near-total misfire that ranks alongside other DC duds like Wonder Woman 1984, Joker: Folie à Deux, and even Black Adam. What's more is that it's a lot more boring than its "intergalactic quest for revenge" story implies thanks to its terrible script, and the stunt appearances by Superman and Lobo don't help very much either. It all adds up to a movie that, at best, clearly doesn't have broad appeal... but those who enjoyed this one will love Warner Bros.' 4K and Blu-ray editions, which both offer comparatively great A/V merits and a bunch of lightweight bonus features. I obviously can't recommend it sight unseen, though.
