Synopsis

High school graduates and best friends Jo and Raissa celebrate their final night together when a mysterious portal whisks them to the fantastical island of Nakali. There they learn that the price of returning home is the gradual erasure of every shared memory they hold.

As the island’s wonders unfold, the pair must navigate shifting landscapes, quirky inhabitants, and a ticking clock that threatens to wipe their friendship from existence, forcing them to decide what they are willing to sacrifice to stay together.

Forgotten Island: A Memory‑Driven Adventure

Forgotten Island arrives in theaters as a bright, high‑concept animated feature that asks what happens when the price of escape is the very bond that holds two friends together. Director Januel Mercado, working from a script by Joel Crawford, Mercado himself, and Simon Wells, builds a world called Nakali that feels both familiar and freshly imagined.

Direction & Visuals

Mercado’s direction leans heavily on color‑coded environments to signal emotional shifts. The island’s jungles pulse with neon flora, while the memory‑draining caverns turn monochrome, a visual shorthand that works well for younger viewers but occasionally feels heavy‑handed for older audiences. The animation is fluid, especially during the portal‑travel sequences, yet some background characters suffer from limited rigging, making crowd scenes look static.

Voice Cast & Chemistry

The lead duo, H.E.R. as Jo and Liza Soberano as Raissa, deliver a naturalistic rapport that anchors the film’s emotional core. Their banter feels unscripted, and the subtle cracks in their voices during the memory‑loss moments are the film’s strongest acting beats. Supporting turns from Dave Franco (Raww), Lea Salonga (Manang), and a lively ensemble including Jenny Slate, Manny Jacinto, Dolly de Leon, Jo Koy, Ronny Chieng, and Kevin McCann add texture, though a few side characters are reduced to one‑note comic relief.

Story & Themes

The premise — two graduates confronting a literal cost for leaving a fantasy realm — is compelling, and the screenplay wisely avoids a simple “memory‑wipe” reset. Instead, it forces Jo and Raissa to choose which moments to sacrifice, turning the climax into a series of micro‑decisions rather than a single spectacle. However, the middle act drags with repetitive puzzle‑solving that does not advance character growth, and the resolution leans on a convenient magical loophole that undercuts the stakes built earlier.

Score, Humor & Pacing

The soundtrack blends orchestral swells with contemporary pop cues, a mix that feels timely but occasionally clashes with the film’s more mythic tone. Comic beats, largely carried by Jo Koy’s Datu and Ronny Chieng’s King Truffle Wuffle, land consistently for the target demographic, yet the humor sometimes undercuts the gravity of the memory‑loss stakes, creating tonal whiplash. Pacing improves in the final act, where the race against forgetting becomes a genuine ticking‑clock, but the earlier exposition‑heavy scenes could have been trimmed by ten minutes without loss.

In sum, Forgotten Island is an ambitious family adventure that succeeds more in concept than in consistent execution. It delivers memorable visual set pieces and a pair of lead performances worth watching, yet its uneven pacing and a reliance on a deus‑ex‑machina ending prevent it from reaching the emotional heights of its clearest inspirations.

Pros

  • Striking color‑coded visual design that conveys emotion
  • Natural chemistry between H.E.R. and Liza Soberano
  • Inventive memory‑loss stakes that drive character choices
  • Energetic comedic support from Jo Koy and Ronny Chieng

Cons

  • Middle act drags with repetitive puzzle sequences
  • Resolution relies on a deus‑ex‑machina that weakens stakes
  • Tonal whiplash between humor and serious memory‑loss moments
  • Some background animation feels under‑developed

Verdict

Forgotten Island offers a visually striking, heartfelt premise anchored by strong lead performances, but uneven pacing and a convenient ending keep it from fully delivering on its emotional promise. It’s a solid family watch that sparks conversation about memory and friendship, though it falls short of the genre’s top tier.
