As for the discussions on Luz not growing enough, I get touchy a bit to be honest cause of what is being suggested.
As from a particular detail I'll get to in a moment, but I don't know about having a breeze all throughout.
Like finding out that she helped Philip to power and resolving to remain in the human realm instead of going back after things were settled. Heck, that bit in class when commenting on a guy who shared her mistake and the response "Maybe he shouldn't exist"? Basically having suicidal thoughts.
And as for what I feel these discussions build up to, on account some have directly said so is that apparently the only satisfying way for her growth to occur is to have her either stay in the Isles with no access to the Human Realm, but that would apparently mean she hides in a fantasy world for life.* Or Human Realm with no access to the Isles. You know "maturity". Kind of like Amphibia.
Now stories like that which treat staying in your world to achieve adulthood can be done well like yeah Amphibia. But the heart of that message is still shaky.
Kind of like those who insist that adults need to drop animation, video games, comic books and such to demonstrate growth. But taking life serious doesn't mean that an adult is beyond flaws and a brand of immaturity.
(*) Besides, if the world of magic and such exists within a story, it's not exactly fantasy. Which kind of makes the claim that main character is literally trapped in one a bit disingenuous.
I really appreciate you bringing this up, because yeah, the conversation around Luz "not growing enough" does start to feel a bit loaded after a while. It's not just a question of whether a character develops, but how we measure that development—and honestly, a lot of the expectations people place on her can feel narrow or even dismissive of the complexity the show is actually tackling.
That moment where she realizes she helped Philip rise to power is huge. It's not a breezy arc at all—she's grappling with guilt, with the implications of her choices, and seriously questioning her worth. The “Maybe he shouldn’t exist” line? That’s raw, and yeah, it’s touching on suicidal ideation. Luz is a kid shouldering a weight that would break a lot of adults, and to me, that is growth: facing mistakes, fear, even despair—and still choosing to keep going, to make things right.
As for the idea that she needs to pick one world to "mature"—whether that's the Boiling Isles or the Human Realm—it does feel like people are leaning into a very rigid, even moralistic, take on what growing up is supposed to look like. Like you said, it echoes that tired notion that adults need to give up animation, games, or anything deemed "childish" to be taken seriously. But The Owl House has always been about embracing identity in all its weird, creative, messy, emotional glory. Luz doesn’t have to abandon the fantasy to grow; she just learns how to carry the lessons and losses from both worlds into her future.
At first, the Boiling Isles is escapism for Luz. It’s a place where she can run from the expectations and judgments of the human world, where fantasy seems to bend to her imagination. But as the story unfolds, it stops being her personal retreat. She realizes it’s not her own private narrative—it’s a real world, with real people, real consequences, and challenges she can’t control or fix with cleverness alone. The fantasy becomes reality, and that shift is crucial. Luz isn’t hiding anymore—she’s choosing to engage with a world that doesn’t revolve around her, that pushes back, that hurts, that helps her grow. That’s not immaturity. That’s growth through integration, not escape.
