The MCU already proved it knew how to build a universe.
That is what makes the later problems so frustrating.
Marvel knew how to introduce characters. It knew how to set up future stories without making the current movie feel like a commercial for the next one. It knew how to take comic-book material and translate it into the MCU without trying to copy every panel, every issue, and every piece of continuity.
Because let’s be honest: adapting these comic arcs panel by panel would never work.
Most of these stories were told across multiple issues, sometimes across multiple titles, and often with characters the MCU did not even have access to yet. If Marvel tried to copy them exactly, the movies would either be impossible to follow or six hours long before the second act even got moving.
So adaptation was always the job.
And for a long time, Marvel was good at it.
They built toward The Avengers. They introduced separate characters, gave them their own lanes, and then brought them together. It was not perfect, but it worked because the pieces had room to breathe before they were thrown into the same room.
They adapted The Winter Soldier without copying the comics exactly. They adapted Civil War without having the same number of heroes or the same comic-book setup. They used Age of Ultron as a version of the Ultron idea that fit the MCU. Then they built the Infinity Saga into a giant payoff that worked because audiences had been following the pieces for years.
That is the proof.
Marvel knew how to do this.
The pattern was simple:
Introduce the characters.
Let the audience understand them.
Find the spine of the comic story.
Translate it into the MCU.
Change what needed to be changed.
Let the consequences build forward.
That was the formula.
Not copying.
Adapting.
And that is why the post-Endgame era became so frustrating. The MCU did not suddenly lose access to good characters. It did not suddenly run out of comic-book material. It did not suddenly become impossible to make superhero stories work.
The machine just got too big.
More movies. More shows. More characters. More setups. More branches. More future teams. More “look, this connects to that.” Eventually the MCU started feeling less like a story universe and more like a scheduling board.
The earlier MCU had setup too. Of course it did. Nick Fury showing up at the end of Iron Man was setup. The Tesseract was setup. Thanos was setup. But most of those earlier projects still remembered that the current movie had to work on its own.
Later, too many projects started feeling like they existed to stock the shelves.
That is where Marvel started screwing the pooch.
Take Black Widow.
Scarlett Johansson should have had that movie earlier. Not after Natasha Romanoff was already dead. Not after the audience had already reached the end of her story.
The better placement would have been between Infinity War and Endgame.
That was the emotional gap. The Avengers had lost. Half the universe was gone. The remaining heroes were broken, scattered, and trying to figure out what was left. That would have been the perfect time to show what Natasha was doing while everything had fallen apart.
That could have made her sacrifice in Endgame hit even harder.
This is not about saying Captain Marvel should not have existed. It is about saying the MCU had an active, beloved character sitting right there, and her story would have mattered more before her ending than after it.
Instead, Black Widow came too late.
That is a pattern problem.
Then came the expansion problem.
Eternals is a good example.
The issue is not that cosmic Marvel cannot work. Guardians of the Galaxy already proved that it could. Audiences accepted a talking raccoon, a tree, a green assassin, a revenge-driven musclehead, and a space outlaw because the movie knew what it was. It was weird, but it had a clean emotional doorway.
Eternals had potential, but it felt like Marvel tried to install too much mythology all at once. Ancient beings living secretly on Earth for thousands of years. Celestials. Deviants. Hidden history. Cosmic judgment. A whole team of new characters. A giant explanation for why they had supposedly been around forever without getting involved in anything we had already watched.
That could have worked with more patience.
Instead, it felt like a massive expansion pack.
And that is not the same as world-building.
World-building makes the universe feel alive.
Franchise-loading makes the universe feel crowded.
Then there is Shang-Chi and the Legend of the Ten Rings.
To be fair, Shang-Chi worked better than a lot of the post-Endgame material. Simu Liu carried the lead role well, Tony Leung gave Wenwu weight, and the movie had personality.
But even there, you can see Marvel rerouting old material into new expansion territory.
The Ten Rings had been sitting in the MCU since Iron Man. It was tied to Tony Stark’s origin. The Mandarin was traditionally an Iron Man villain. Then the MCU played games with that through Iron Man 3, and later reworked the whole idea into Shang-Chi’s family mythology.
That does not make Shang-Chi a bad movie.
It just shows how Marvel had started pulling older threads into new corners instead of always resolving consequences where they started.
Sometimes that works.
Sometimes it feels like a retrofit.
And once Disney+ became part of the machine, that retrofit feeling got worse.
Suddenly, the MCU was not just movies anymore. It was movies, shows, returning rights, new characters, old properties, streaming demand, future teams, and post-Endgame rebuilding all happening at once.
That is a lot of machinery.
And machinery does not automatically produce story.
That is the real problem.
Marvel had a pattern that worked:
Take the comic idea.
Find the story spine.
Translate it into the MCU.
Respect what the audience already watched.
Let consequences build forward.
Somewhere along the way, that became:
Find the character.
Find the hook.
Find the slot.
Find the Disney+ branch.
Find the future team setup.
Find a way to make it all connect.
That is not the same thing.
Adaptation asks, “How does this idea work inside the world we built?”
Installation asks, “How do we get this character or concept onto the board?”
Audiences can feel the difference.
That is why the post-Endgame era felt weaker. Not because superheroes suddenly became impossible to enjoy. Not because every new character was doomed. Not because the comics were sacred and untouchable.
It felt weaker because the MCU became too aware of its own machinery.
Too many projects started to feel like they were serving the franchise map before serving the story. Once that happens, people stop feeling like they are watching consequences. They start feeling like they are watching content management.
That is the real falloff.
Marvel did not forget how to make superhero movies.
Marvel forgot the discipline that made its best adaptations work.
Please refer to the upcoming articles on She-Hulk, Ironheart, Ms. Marvel, Hawkeye, and several other MCU projects where this same pattern shows up in different ways. Each one has its own problems, but they all point back to the same larger issue: Marvel had a working adaptation model, and then the machine got too crowded.
