The Superhero Cycle Nobody Admits Repeats

Supergirl flopped because audiences had already made a decision about superhero investment before the film existed.

That decision wasn't about the character or the script. It was about the sheer tonnage of universe-building required to make a supporting player matter.

This is the fourth time we've watched this pattern unfold and blamed it on something else. The 1960s Batman TV show saturated the market so completely that the property became toxic for nearly two decades.

The 1990s Batman films—beginning with Burton and collapsing by Schumacher—didn't fail because the movies got worse. They failed because audiences had been asked to show up for five Batman films, three Penguin storylines, two Catwoman versions. A Robin origin in six years. Fatigue masqueraded as creative decline. Then 2008 reset everything—Iron Man worked not because it was better than prior superhero films. Because it was the first in a new cycle.

The Marvel Cinematic Universe and DC's multiverse approach solved the wrong problem. They treated the 1990s collapse as a creative crisis instead of a saturation crisis—so they poured resources into writing better minor-character films and demanding that audiences care about 40 interconnected characters across 12 franchises. They made the exact same mistake, more expensive. Supergirl arrived into a market where the threshold for new-character investment had already been crossed. The film didn't fail—the model did.

Studios are now asking whether they need better writers or different characters. They should be asking whether they need fewer films. But that question requires admitting that the problem isn't creative execution. It's constraint. And no executive wants to hear that making less money per year saves the franchise long-term.
