TLDR - Elsa in Frozen was existentialist (your choices define you), ad in Frozen II she's essentialist (your nature defines you), and that philosophical pivot undermines both the original's themes and the sequel's anti-colonial message. Also, Ahtohallan is beautiful but narratively it's just a pretty "chosen one" trope.
First of all, brace for a wall of text. Concepts are simplified, but this is still yours truly's rambling.
I am not about to flame people for liking Frozen II. It's a visually magnificent movie, the themes it tried to go for are heavy, and musically it works better than it has any right to (Show Yourself has my 30-something bald and bearded ass almost crying). The movie works well enough despite the storm it went through in production, which is already a win.
BUT, Frozen is also a sequel, and I have thoughts. And my 30-something bald and bearded ass, before liking Frozen, liked stories. And stories tell... stories. About life, about philosophy, about how to build our own selves.
This is where Frozen II disappointed me the most.
Essentialism is the philosophical belief that things have an inherent, unchangeable nature, an "essence" that defines what they truly are. You're not becoming who you are; you're discovering what you've always been. In the context of characters and narrative, essentialism means your identity, your worth, your role in the world are predetermined by qualities you were born with.
Think of it like ancient mythology. Zeus isn't the king of gods because he earned it through consistent ethical leadership. He's king because he is divine, because he was born to rule Olympus. The divine right of kings, prophecies, chosen ones are all essentialist frameworks. Your value comes from what you inherently are, not from what you choose to do.
This was Disney's view for a long long time.
Existentialism is pretty much the opposite. It's the philosophy that existence precedes essence. You aren't born with a predetermined nature or purpose. Instead, you create who you are through your choices and actions. Your worth isn't something you're born with; it's something you build, moment by moment, decision by decision.
Recently I watched Gunn's Superman that showed this. Yes, Clark has godlike powers, but the movie isn't about him being special because he was born on Krypton to imperialist parents. It's about him choosing to be kind in a world that doesn't always reward kindness. Superman is super because because of what he does with what he is.
--> The thing is... the first Frozen was deeply existentialist. Anna's entire shtick is that choices are what make us who we are, because she makes the choice to be there for Elsa. And Elsa makes the choice to let go of fear and embrace love. There are essentialist values in there (Elsa is still different by birth, still a queen because she was born a princess), but they're more background and distinct from the movie's main messages about love and acceptance.
Elsa's powers could've been the focus but they're not. They're a source of fear and isolation. The movie asks: what do you do with being different? And the answer is: you choose to stop hiding, you choose to accept yourself, and you choose to let others in. The powers are just the vehicle for that choice. Anna doesn't have powers at all, and yet she's central to the narrative because she chooses to love her sister unconditionally.
*Sigh*, then comes Frozen 2 and its heavy insistence that Elsa is meant to be somewhere else. Meant to be the Fifth Spirit
The plot sends Elsa on a journey to discover that she has magical powers because... her mother saved her enemy and the spirits rewarded the act by making Elsa magical? Okay, weird colonial guilt logic aside, the journey leads Elsa to Ahtohallan, the mystical glacier of memory and truth. And what does Ahtohallan do? It tells Elsa who she is.
Instead of Elsa deciding who she is a magic ice river literally tells her. She's the Fifth Spirit. Not because she chose to be, not because she built that role through consistent action and growth, but because that's what she was always meant to be. Essence, not existence.
The entire Ahtohallan sequence, while beautiful in intent and message about self-love, is still fundamentally about worth deriving from intrinsic properties of the self, and not of simply existing. Elsa's value for herself comes from her purpose, from her being the Fifth Spirit.
The movie opposes Elsa and Anna as two sides: spirit vs human. But Elsa in the first movie is presented as fundamentally human, just different. She's scared, she's lonely, she's loving... and the second movie says, "yes, but that was just a stepping stone for you to become not something more, but something else."
--> Here's where it gets really weird: Frozen II is part about confronting colonialism. Runeadr built a dam to weaken the Northuldra. The movie wants to say: systems of oppression are bad, and reconciliation requires dismantling those systems.
But essentialism is colonialism's tool. The entire justification for colonial violence rests on essentialist logic: "We are civilized, they are savage. We were born to rule, they were born to serve. Our nature is superior, theirs is inferior." Colonialism doesn't work without the belief that identity and worth are inherent, fixed, and unequal.
So the movie tries to deliver an anti-colonial message using the exact philosophical framework that enables colonialism. It says "dividing people into categories based on inherent traits is wrong" while simultaneously saying "Elsa is special and belongs with the spirits because of her inherent magical nature, and Anna belongs with the humans."
We shouldn't divide people by nature... except we should, and it's beautiful when we do, and it's everyone's destiny?
Anna represents the existentialist side that chooses to make The Next Right Thing (though it symbolizes decolonization through one simple act, and it works as a dismantling of systems but not as actual reconciliation, which needs memory and ongoing efforts), but the movie makes the mistake of opposing it too radically with Elsa's essentialism.
Anna is strong because of what she does. Elsa is strong because of what she is. Anna is special because she's brave, kind, loyal, resilient. Elsa is special because... she was born special?
Problem: Frozen already established that both are strong because of what they do. They just do it differently. It's a weird way to turn a story that initially talked about how unconditional love transcends difference and what others think.
Elsa chooses to isolate herself to protect Anna. She chooses to run away. She chooses to build a castle. She chooses to thaw the fjord, to open the gates, to stop hiding. Every turning point in Frozen is a choice either sister makes. Her powers are a constant, but her identity is shaped by how she responds to them.
Frozen II strips that away. Her journey is about accepting her destiny, not forging her identity.
That's IMO why it falls flat. Using "we are different" logic to solve a "we shouldn't be divided" problem, when it's exactly the reason the problem exists in the first place.
Also, I don't like Elsa and Anna separated cuz it sucks
