I don’t think it needs to be re-written

I would change role of Ikaris and Ajak. He would be protagonist alongside Sersi and Ajak would be antagonist.

There are multiple ways to do it.

Before Eternals came out, I was concerned about the premise of “group of powerful people choose not to get involved in anything over 7,000 years”.

This is what I thought of back then.

It’s more of a re-imagining than a reworking of what we got:

Olympia is real.

It was a planet 7,000 years ago.

But the planet was ravaged by the Deviants a race of intergalactic marauders (not unlike the Chitauri).

The Eternals: Sersi, Ajak, Ikaris, Sprite, Kingo, Thena, Gilgamesh, Druig, Phastos, & Makkari are a selection of random citizens from Olympia.

7,000 years ago, Olympia was decimated by the Deviants,

They killed all of the Olympians.

Only Sersi & Co survived.

Before the Deviant attack, they all had their powers relating to Cosmic Energy.

But the Deviants released a bio-weapon that indefinitely blocked all of the Eternals’ powers (except immortality).

Arishem found them and took pity on them.

He saved them and helped them escape to Earth.

A batch of Deviants followed them there but got trapped in arctic ice.

The Eternals lived among Humans for 7,000 years, just trying to blend in and begin a new life. They didn’t have to “avoid interfering in human history.”

They interfered often — but they had no powers, so they never stood out.

That’s why they never reached out to the Avengers.

They had no powers, there wasn't much they could do, they wanted to live normal lives, and they believed there weren’t any Deviants on Earth.

Then Infinity War happened and all ten Eternals got snapped.

The Deviants in the Ice got snapped too.

When the Avengers brought everyone back, the Eternals returned WITH THEIR OLD POWERS. The Deviants returned outside of the ice, free for the first time in 7,000 years.

So the Eternals movie follows these Deviants trying to prey on the Human Race and call to their empire — and the newly powered Eternals trying to stop them.

This way:

• The Eternals can be superheroes now without calling their inaction in history into question.

• The Eternals’ lack of involvement in history is because they’re powerless, not because of some arbitrary rule.

• The Eternals’ randomness is because they’re a random assortment of refugees from Olympia, rather than a strangely arbitrary selection by Arishem.

However, this story didn’t account for the Celestials and the Emergence, which I didn’t know about at the time.

Focus on Ikaris heel turn way earlier on in the storyline, I would ended the Deviants arc during the 1st act.

Also as a side I would somehow Dusted all ten Eternals and maybe Arshiem as well.

Keep in mind that Eternals is not only my favorite MCU film, it's also my favorite film of all time, and I think it's nearly perfect, so this would be to make it even more perfect (to me):

-I would space out the flashbacks a little bit more, because it bothers me that we get two flashbacks (of the Eternals in Babylon in 575 BC and then the Tenochtitlan scene in 1521) way too close to each other.

-I would change the revelation of the Eternals being "fancy robots" to another scene. That way, when Arishem reveals the Emergence, the scene is not as long and the impact of the true mission is bigger. And then, Sersi would have another talk with Arishem, which would be frightening, because he would be aware of them trying to stop the Emergence, and that's when he would reveal they're robots.

-I would try to make it more obvious that Kro and the Deviants are not and were never supposed to be the "main antagonists". People seem convinced they were not handled properly; that Kro (and Bill Skarsgard) was wasted as a villain, and it's something that stops them from enjoying the film and reveal of the true antagonist. When in reality, Kro and the Deviants were only supposed to be a mirror of the Eternals, another pawn by Arishem and a tool of Ikaris. Perhaps another line of dialogue at the end could've solved this.

-Finally, I would remove the inclusion of Blade's voice off in the final scene, leaving Dane just touching the Ebony Blade. And I have some issues with Pip the Troll and Eros appearing in the first post-credits scene, but I'm not really knowledgeable in comics to know how to fix it.

Sersi vs Thanos up next

I loved the movie, idk maybe kill off less 🤷‍♂️

I would have made this into a show with at least 8 episodes. I loved the movie. The cinematography was awesome. And I cared about all the characters. But they introduced TEN new heroes plus a smattering of supporting characters. There was not enough time in one film to really get into each of those characters. I just wanted more time with them.

I think there was too much potential to be contained in one movie. It might've been better as a series with 40-minute episodes, give it more time to flesh out each character and show the story from more perspectives.

I would make it not exist
