The audience that actually bought tickets for Supergirl handed it a grade this weekend, and it’s not the grade James Gunn, Peter Safran, Warner Bros., and DC Studios were hoping for.
Supergirl opened to a B- CinemaScore. In the context of recent comic book movies, that number stings.
A B- lands below Marvel Studios’ The Marvels (B), the film everyone points to as the low-water mark of the MCU. It also comes in under DC’s own The Flash (B), Aquaman and the Lost Kingdom (B), the 2011 Green Lantern (B), and Shazam: Fury of the Gods (B+).
When the people who showed up grade your summer tentpole below the titles routinely cited as the genre’s bottom, the problem isn’t the audience that stayed home.
The PostTrak numbers back it up
Screen Engine’s PostTrak tells the same story. The definite recommend figure landed at 52%, which is soft for a planned event movie of this size.
The gender split is the tell.
Men made up nearly 60% of the opening crowd at 59%, but only 45% said they’d definitely recommend it. Women, at 41% of the audience, came in higher at 62%.
Either way, this is a movie that didn’t send its opening-weekend crowd out the door selling it to anyone else.
Supergirl is tracking for around $40 million domestic, losing the frame to Toy Story 5 in its second weekend, right inside the window tracking had been flagging for weeks.

The demos are where the marketing math falls apart
Men over 25 led the audience at 41%. Women over 25 followed at 26%, men under 25 at 18%, and women under 25 sat at the bottom at 15%.
The old rule is that you need three demographics turning out to have a hit. Supergirl got older men and not much else.
That’s the exact outcome Warner Bros. spent money trying to avoid.
The studio ran a heavy push at younger women, including a tie-in with Ulta Beauty. The under-25 female demo is precisely the group that didn’t buy a ticket.
Predictably, that no-show is already being spun into a story about fans and women not showing up for the movie.
The draw wasn’t the lead, either. On PostTrak, only 26% of moviegoers said Milly Alcock as Kara Zor-El was the reason they came. Nearly twice as many, 49%, said they showed up because it’s part of a franchise they follow.

Reading the B-
Keep in mind that CinemaScore only surveys opening-night ticket buyers. The B- is how the hardcore fans who showed up felt, and they weren’t sold.
That’s the part the spin can’t get around. CinemaScore comes from the people who paid to see it first.
For a comic book movie launching a major DC character under the new regime, a B- isn’t just soft. It’s a warning sign.
The opening was already weak, the demos missed the target, the recommend score is lukewarm, and the hardcore crowd didn’t give it the kind of grade that fuels a second weekend.
So no, the audience didn’t fail Supergirl. Supergirl failed to give the audience enough reason to show up, and the people who did show up didn’t exactly leave cheering.
