Major spoilers ahead.
Okay.
Before we discuss The Substance ending, I would just like to point out that the instructions were VERY clear.
Seven days. Switch. No exceptions.
That’s it.
Nobody asked Elisabeth and Sue to solve calculus. Nobody gave them a 48-page IKEA manual with three missing screws.
Seven days.
And somehow these two turned that simple arrangement into one of the nastiest workplace disputes I have ever witnessed.
By the time The Substance reaches its finale, Elisabeth Sparkle and Sue have completely destroyed each other in their desperate attempt to hold onto youth, beauty and attention.
And then the movie says:
Actually, we’re just getting started.
Why Is Elisabeth So Horribly Aged?
The Substance creates Sue as a younger version of Elisabeth, but the movie repeatedly tells us one important thing:
They are one.
They may have separate bodies, but Sue isn’t some random younger woman who moved into Elisabeth’s bathroom.
Sue is Elisabeth.
The rules require them to switch every seven days.
While Sue is active, Elisabeth’s body remains unconscious. Sue also needs stabilizing fluid taken from Elisabeth’s body.
The problem begins when Sue decides seven days simply isn’t enough.
Because apparently once you become young, gorgeous and famous, calendars become suggestions.
Sue keeps staying awake longer and taking more stabilizer than she’s supposed to.
Every extra day has consequences for Elisabeth.
First, Elisabeth wakes up with an aged finger.
Then it gets worse.
Much worse.
And the damage cannot be reversed.
By the end, Elisabeth has been physically destroyed by Sue’s repeated abuse of the process.
But remember:
Sue is doing this to Elisabeth, and Elisabeth is doing this to herself.
That is the tragedy.
Why Doesn’t Elisabeth Just Stop Using The Substance?
Because Elisabeth hates being Elisabeth.
That’s really the whole movie.
When Elisabeth is herself, she feels discarded.
When she’s Sue, everybody wants her.
Sue gets the television show.
Sue gets the attention.
Sue gets the billboards.
Sue gets told she’s perfect.
So even when Elisabeth sees that The Substance is destroying her body, she keeps going back.
And that is what makes the movie so uncomfortable.
Elisabeth knows exactly what’s happening.
She just prefers destroying herself to returning to a life where she no longer feels valued.
Whew.
This movie did not come here to play with anybody’s self-esteem.
Why Does Elisabeth Try to Kill Sue?
Eventually Sue takes things way too far.
She stays active for months while preparing to host a huge New Year’s Eve television event.
But there’s a problem.
She eventually runs out of stabilizer.
No stabilizer means Sue cannot keep going.
She is forced to switch back.
And when Elisabeth wakes up and sees what Sue has done to her?
Baby.
She is DONE.
Elisabeth contacts the Substance supplier and asks how to end the experiment.
She’s given a termination serum that will permanently kill Sue.
Elisabeth injects Sue with it.
For a moment, it looks like she’s finally ready to end this nightmare.
Then Elisabeth stops.
Because even after everything Sue has done, Elisabeth still cannot let go of the younger version of herself.
She revives Sue.
And this decision immediately becomes everybody’s problem.
Why Are Elisabeth and Sue Awake at the Same Time?
Under normal circumstances, only one of them can be conscious at a time.
But Elisabeth interrupts the termination process and brings Sue back before it’s completed.
Something goes wrong.
Now both Elisabeth and Sue are awake.
At the same time.
And after the entire movie keeps insisting:
YOU ARE ONE
these two look at each other and basically decide:
No we’re not. Square up.
They fight.
And it is ugly.
Sue takes all her anger, resentment and fear out on Elisabeth.
Eventually, Sue kills her.
Which seems like Sue winning.
Except—
Ma’am.
You just murdered the body supplying the stabilizer keeping YOU alive.
This is why we think before committing homicide.
Why Does Sue Start Falling Apart?
Sue rushes to get ready for the New Year’s Eve show.
She has everything she wanted.
Fame.
Youth.
Beauty.
A massive audience.
And Elisabeth is finally gone.
Except Sue immediately begins deteriorating.
Her body starts breaking down.
Teeth come loose.
Her body fails.
She cannot maintain the perfection everyone expects from her.
And because Sue has learned absolutely nothing, she decides to inject herself with the original activating Substance.
Now let me remind everybody:
That is NOT what you’re supposed to do.
The Substance creates a new version of you.
Sue is already the new version.
So when she injects herself again?
The process produces something else entirely.
Ladies and gentlemen…
Monstro Elisasue has entered the chat.
What Is Monstro Elisasue?
Monstro Elisasue is a grotesque combination of Elisabeth and Sue.
She’s enormous.
Misshapen.
Covered in mismatched body parts.
And Elisabeth’s face is literally embedded into the creature.
It is basically every physical insecurity Elisabeth has been running from smashed together into one body.
And somehow, this is the first time in the entire movie that she begins accepting herself.
Which is WILD.
Elisabeth had Demi Moore’s face and couldn’t love herself.
Sue looked like Margaret Qualley and couldn’t love herself.
But after becoming a walking pile of flesh with a face growing out the back?
Suddenly:
You know what? I deserve to be seen.
Ma’am.
Therapy was available.
Why Does Monstro Elisasue Go Onstage?
Because she still wants the audience’s love.
Even after everything.
She covers herself, attempts to recreate Elisabeth’s appearance and walks onto the New Year’s Eve stage.
She wants the crowd to accept her.
But instead of seeing the star they were expecting, the audience sees a monster.
And they turn on her.
Immediately.
Which is kind of the entire point.
This industry loved Elisabeth when she fit its definition of desirable.
Then it discarded her.
It loved Sue because Sue represented the new perfect woman.
But the second Sue stops looking perfect?
The love disappears again.
The audience never loved her.
They loved what she looked like.
Why Is There So Much Blood?
Then the movie loses whatever little bit of restraint it had left.
Monstro Elisasue’s body ruptures and unleashes an absolutely ridiculous amount of blood across the audience.
And I mean EVERYBODY gets baptized.
Harvey.
The audience.
The walls.
The stage.
If you bought a ticket in the first 15 rows, congratulations, you are now wearing Elisabeth Sparkle.
Director Coralie Fargeat has explained that the blood spraying onto the crowd is intentional symbolism.
The audience represents the culture that helped create this violence in the first place.
They demanded perfection.
They consumed these women.
They judged them.
They discarded them.
So the violence gets thrown right back at them.
In other words:
Oh, you wanted a spectacle? HERE.
What Happens to Elisabeth at the Very End?
After Monstro Elisasue’s body collapses, almost nothing remains.
But Elisabeth’s face survives.
That tiny piece of Elisabeth crawls toward her star on the Hollywood Walk of Fame.
She reaches it.
And for one final moment, Elisabeth imagines or experiences the adoration she spent her whole life chasing.
Then she melts away.
Eventually, there’s essentially nothing left.
Elisabeth Sparkle spent the entire movie destroying herself trying to remain worthy of a star with her name on it.
And in the end?
The star remains.
She doesn’t.
That’s cold.
So What Does The Substance Ending Actually Mean?
My read?
The movie isn’t simply saying:
Hollywood is mean to older women.
That’s part of it.
But it’s also about what happens when you internalize those expectations so deeply that you become the person hurting yourself.
Elisabeth didn’t invent ageism.
She didn’t create Hollywood’s obsession with youth.
She didn’t create a culture that tells women their value decreases as they age.
But she absorbed those messages until she believed them herself.
That’s why Sue and Elisabeth constantly talk about each other like they’re separate enemies even though the Substance keeps reminding them:
You are one.
Sue hates Elisabeth.
Elisabeth hates Sue.
But it’s really self-hatred fighting itself.
And nobody wins.
Why Is Monstro Elisasue Important?
Here’s the part I really love.
Monstro Elisasue is physically the furthest thing possible from everything Elisabeth thought she needed to be.
Yet according to Fargeat’s explanation of the ending, this is finally the moment when the character experiences a kind of freedom from obsessing over her appearance.
She looks at herself and doesn’t immediately reject what she sees.
For the first time, she decides:
This is me. I’m going out there anyway.
Unfortunately, this breakthrough comes approximately two hours, several hundred gallons of bodily fluid and one dead alternate self too late.
But growth is growth.
My Take
The Substance has one of those endings where you sit there during the credits thinking:
I have several questions, but I’m also afraid to ask them.
What starts as a movie about an aging celebrity becomes this completely bonkers fairy tale about beauty, fame, addiction and self-hatred.
And that final monster isn’t scary just because she’s grotesque.
She’s scary because she’s the physical result of everything Elisabeth believed about herself.
She kept trying to cut away the version she thought wasn’t good enough.
Older.
Younger.
Prettier.
Uglier.
Elisabeth kept dividing herself until there was almost nothing left.
Meanwhile, the movie had been screaming the answer at her from the beginning:
YOU ARE ONE.
Girl.
They put it on the package.
Horror Tea Rating: ☕☕☕☕½
Four and a half Tea Cups.
One half-cup deducted because I am still emotionally processing that New Year’s Eve audience getting pressure washed with somebody’s entire circulatory system.
Other than that?
No notes.
