Supergirl: HBO Max Release Date Revealed For DC Studios Movie With Just 53% On Rotten Tomatoes

Supergirl was a critical and commercial misfire for DC Studios, but for any DC Comics fans who have been waiting to watch the movie at home, its HBO Max premiere date has now been revealed.

DC Studios' Supergirl will make its global streaming debut exclusively on HBO Max on Thursday, September 10. The film will also debut on HBO linear on Saturday, September 1 at 8 pm ET.

A version of Supergirl with American Sign Language (ASL) will also stream exclusively on HBO Max the same day, performed by Catalene Sacchetti (Songs in Sign Language) and directed by Jonaz McMillan (The Pitt with ASL Season 1).

The movie has 53% on Rotten Tomatoes and a 72% Audience Score on the "Popcornmeter." The second DCU movie grossed $126 million on a reported $180 million production budget. The marketing spend was approximately $100 million. 

In its inaugural flight into the new DC Cinematic Universe, Supergirl reveals the origin of the interplanetary nomad Kara Zor-El, a.k.a. Supergirl, cousin of Kal-El, better known as Superman. Headstrong, worldly-wise, and often reckless, Supergirl exudes a brand of heroism all her own—truthful, relatable, and always on her own terms.

But when an unexpected and ruthless adversary strikes too close to home, Kara reluctantly joins forces with an unlikely companion. Together they undertake an epic, interstellar journey, struggling to balance one's need for vengeance with the pursuit of justice—and to save the life of Kara’s best friend, her dog Krypto. Ultimately, Supergirl will prove that doing good can be tough... and it doesn’t always have to be nice.

Supergirl stars Milly Alcock, Matthias Schoenaerts, Eve Ridley, David Krumholtz, Emily Beecham, David Corenswet, and Jason Momoa. 

The film is written by Ana Nogueira and directed by Craig Gillespie. DC Studios heads Peter Safran and James Gunn produced the film, which is based on characters from DC; Supergirl is based on characters created by Jerry Siegel and Joe Shuster. The film is executive produced by Nigel Gostelow, Chantal Nong Vo, and Lars P. Winther.

In my review, I concluded, "Bad writing, gratuitous cameos, and uninspired visuals take us back to the bad old days of the DCEU in Supergirl, a showcase for the super-talented Milly Alcock, but Kryptonite to anyone who likes good superhero movies."

However, ComicBookMovie.com owner Nate Best countered, "For me, it's a 7 out of 10. Call it a 6 if you want me to be stricter, and fair warning, I'm an easy [grader]. The only superhero movie I've ever genuinely wanted to walk out of was Thor: Love and Thunder, and Supergirl isn't remotely in that conversation. It's a fun comic-book movie, and some nights that's exactly enough."

53% RT? That’s pretty generous.

I gave it 3/10 stars, and I rounded up.

It's mid grade just like most of the DCEU and half of the MCU. Of course logic doesn't seem to exist lol

@OneMoreTime - not for a very long time. the brand is too tarnished at this point.

i hope The Batman II does but even that is a big ask

@Lisa89 - Aquaman grossing a billion dollars sounds so [frick]ing insane, it must’ve been a glitch in the Matrix.

@MotherGooseUPus - Batman made close to $775 as a reboot, on a limited theatrical run, so a sequel making an additional $225 is not that big of an ask when you think about it.

Honestly , I don’t think it was great or even good film but it’s better then some have said thus “mid” at best imo so like C+\B-…

I felt the flashbacks to both Krypton and Earth were better then the main storyline which needed more emotional heft to it atleast from Ruthye’s side (I wish they kept the deleted sequence of her spending some time with her family prior to their deaths since that endears you to them , atleast to an extent).

However the main highlight of the film was Milly Alcock as Kara who played the trauma , grief aswell as attitude of the character well so I think that was the films main and most important success since even if we don’t get more Supergirl films , I hope we get more of Milly’s Kara in other ways because she’s a star imo!!.

You know, I watched it recently, and I was surprised by how much I actually enjoyed it. Tonally, it’s all over the place and definitely doesn’t all work, but I thought the action was solid and she made for a really cool Supergirl. You can just feel two completely different movies clashing with each other throughout. Definitely not the terrible movie I was expecting, but I wouldn’t call it great either.

They're seriously releasing this ? I thought they were joking; anyone with any business sense would try to hide this movie.
