Growing up rarely ends a friendship in one clean break. More often, it changes the rhythm: someone leaves, familiar routines disappear, and the person who once understood every private joke becomes harder to reach. Forgotten Island gives that ordinary heartbreak a wonderfully extravagant form. Two friends enter a magical world where getting home threatens the memories that made them close. Beneath the creatures and spectacular color is a question with real weight: how do you let a person change without treating that change as abandonment?
The departure for Caltech gives the fantasy a specific imbalance. Raissa is not simply the friend who wants to leave; she has an opportunity that can change her life. Jo is not simply the friend who wants everything to stay the same; her fear has roots in bereavement and an uncertain future. That makes the disagreement harder to dismiss as a misunderstanding waiting for an apology. Each girl can love the other and still want something incompatible with the arrangement that previously made them happy. The island externalizes those competing needs, turning an ordinary transition into a bargain neither can assess without feeling threatened.
Jo and Raissa, voiced by H.E.R. and Liza Soberano, bring different anxieties to that question. Raissa has a future taking shape beyond the Philippines; Jo faces the possibility of being left behind. Directors Januel Mercado and Joel Crawford make Filipino folklore part of the friends' shared imaginative life, rather than a collection of attractions to tour. That distinction gives the adventure an identity. Nakali matters because it belongs to the girls' understanding of each other, and its wonders acquire emotional consequences when their common history becomes something they could lose.
H.E.R. and Soberano have roles that need to remain complementary without becoming interchangeable. Jo's imagination and Raissa's purposefulness give the friendship its friction, but both qualities also explain why the pair belong together. The film benefits from making the bond an active exchange rather than an established fact supplied by the opening. Their shared mythology is a language: they know how to excite, annoy and reassure each other through it. That is why the quieter moments of separation carry more consequence than a conventional announcement that two characters are best friends. The audience needs to understand the specific companionship in danger, not merely approve of friendship as an idea.
The opening montage is crucial to that understanding. Its accumulation of objects and shared experiences makes time visible before the adventure begins, establishing a past that can later become vulnerable. An analog setting gives those memories a physical texture: they exist in things kept, passed between people and handled again. The directors' discussion of the film's changing visual styles and lens choices suggests a deliberate effort to give small experiences cinematic size. This is where the extravagance earns its place. A fantastic landscape can communicate the scale of an emotion that, in the everyday world, arrives through a bracelet or the prospect of an empty room.
The animation pushes the expressive freedom of the team's Puss in Boots: The Last Wish toward an even busier collision of textures, movement and comic invention. It is an exhilarating approach, although the appetite for another flourish can crowd out the feeling a scene has already earned. A friendship this important needs room for hesitation and awkwardness as well as visual fireworks. The published critical split makes sense: what registers as abundance to one viewer can become exhaustion to another, particularly when each new encounter arrives at much the same heightened pitch.
The creatures also carry more interest when their strangeness is connected to the girls' anxieties. Raww, voiced by Dave Franco, supplies the looseness and unreliable guidance expected of a comic companion, while the island's relationship to memory brings a more unsettling appetite into play. The supporting characters are entertaining inventions, but they need not all be equally elaborate to matter. A world can feel richer when an encounter leaves something unexplained. Forgotten Island occasionally behaves as if every new creation deserves another burst of activity, when an odd presence glimpsed briefly could make Nakali feel larger than the portion its plot has time to visit.
Its use of Filipino folklore is particularly valuable because the culture is already present in the protagonists' lives. The fantasy is not an outside visitor arriving to teach them that their heritage matters. It grows out of a world they understand through family stories, language and shared enthusiasm. For viewers unfamiliar with that material, the pleasure is entry into someone else's imaginative vocabulary. For viewers who recognize it, recognition can coexist with surprise. The film's accessibility does not depend on stripping the creatures of their particularity, although the familiar quest mechanics sometimes press their differences into the same succession of obstacle, gag and escape.
The more difficult emotional lesson concerns the ownership of a shared past. Jo and Raissa may remember the same years, but those years cannot oblige them to want the same future. The film is strongest when memory becomes something that helps them recognize each other, rather than evidence one can use to prevent the other from leaving. That is a sophisticated idea for an adventure aimed at younger audiences. Its generous conclusion depends on the possibility that affection can survive a change in form. The noise sometimes obscures that proposition, but the proposition is substantial enough to justify the film's exuberance and the patience it occasionally asks of the viewer.
Yet the central idea is stronger than the occasional clutter around it. Memories are not simply souvenirs here; they are the evidence that a shared life happened, even if that life cannot continue in its original form. The film's emotional appeal comes from taking young friendship seriously without pretending that staying together forever is the only happy outcome. Its familiar adventure structure becomes more interesting when escape means negotiating attachment, rather than merely defeating a threat. That gives the spectacle somewhere meaningful to land, and gives its cultural specificity a purpose beyond novelty.
