GAME-scanner analysis

Supergirl’s upcoming release on HBO Max, scheduled for September 10, 2026, is a key moment for the new DC Universe, led by James Gunn and Peter Safran. With a budget estimated between $170 million and $185 million, the film has so far earned only $126 million, raising questions about the franchise’s viability. Critics, including Clint Gage, have suggested that Milly Alcock’s take on Supergirl is not used enough in the story, which may be contributing to the mixed audience response.

What does this mean for players?

For DC Universe fans, the HBO Max release offers a chance to watch the film at home, which may be appealing given its low 53% Rotten Tomatoes score. That score could temper viewer expectations and may affect the reception of future DC projects. Supergirl’s box office performance could also serve as an indicator of how audiences are responding to the franchise’s new direction.
