Forgotten Island Christian Movie Review

(2026)

Forgotten Island is an animated fantasy adventure about best friends Jo and Raissa, who are transported through a mysterious portal to the fantastical island of Nakali. To return home, they face the threat of losing the memories of their friendship.

This is a family-oriented fantasy with mild peril and emotional stakes, but its portal fantasy and supernatural setting give parents more to discuss than the surface content alone. The strongest discernment point is the film's non-biblical supernatural framework, along with themes of memory, identity, and sacrifice.

Use the content rating for what children will see and hear, and the Christian guidance rating for what the story may teach or normalize.

Content

Content Rating: 4/10

Mild

Surface content looks fairly light for most families. The main concerns are fantasy peril, mild scary moments tied to the island and portal journey, and the emotional distress of possibly forgetting a close friendship. Sexual content, coarse language, and substance material do not stand out here.

Christian Guidance

Christian Guidance: 7/10

Meaningful Guidance

The larger issue is worldview rather than harsh content. The story centers on a mysterious portal, a fantastical island, and supernatural rules about memory and return, all outside a Christian understanding of spiritual reality. Parents may also want to talk about how the film treats identity, attachment, and sacrifice, and how Christian hope in Jesus Christ differs from stories where memory or mystical forces define who we are.

Portal fantasy Mild peril Memory loss theme

Content Indicators

Violence / Intensity

Some

The adventure includes fantasy peril tied to being trapped on a strange island and racing to escape before a permanent loss takes place. The tension sounds more suspenseful than graphic, but younger children may still feel the threat.

Language

Minimal

Strong language does not stand out here, and there is no notable evidence of profanity, crude jokes, or sexual humor.

Sexual Content

Minimal

The central relationship is a close friendship between Jo and Raissa, shaped by affection, loyalty, and fear of separation. Sexual content does not stand out as a notable concern.

Occult / Spiritual

Notable

The story begins when Jo and Raissa are transported through a mysterious portal to the fantastical island of Nakali. That portal-and-realm setup places the adventure inside a supernatural system outside biblical teaching, so parents may want to discuss the difference between fantasy magic and the real spiritual hope found in Jesus Christ.

Faith & Values Conflict

Some

The film's supernatural framework treats portal-based mystical forces as the engine of truth and rescue rather than God's providence.

Cultural Messaging

Minimal

Forgotten Island is presented to value friendship, loyalty, and sacrifice, which can open good conversations about love and faithfulness. At the same time, it places its central conflict inside a supernatural system where a mysterious realm and its rules govern memory, identity, and return. Christian families may want to discuss that our deepest identity is not secured by memories or mystical forces, but by the God who knows us fully and by hope in Jesus Christ.

Sexuality & Gender Themes

Minimal

Sexuality and gender themes are not a feature of this title.

Forgotten Island Christian Movie Review (2026)

Guidance: Talk Together

This is a family-oriented fantasy with mild peril and emotional stakes, but its portal fantasy and supernatural setting give parents more to discuss than the surface content alone. The strongest discernment point is the film’s non-biblical supernatural framework, along with themes of memory, identity, and sacrifice.

Why This Guidance Level

This lands in the middle because the surface content is mild, but the story’s fantasy framework carries more spiritual and worldview weight than a simple adventure. The portal to Nakali, the supernatural rules around memory, and the emotional pressure of losing identity and friendship give parents several worthwhile conversations to have afterward.

Faith & Worldview Perspective

Forgotten Island is presented to value friendship, loyalty, and sacrifice, which can open good conversations about love and faithfulness. At the same time, it places its central conflict inside a supernatural system where a mysterious realm and its rules govern memory, identity, and return. Christian families may want to discuss that our deepest identity is not secured by memories or mystical forces, but by the God who knows us fully and by hope in Jesus Christ.

Truths Reflected

  • The story honors loyal friendship and the pain of separation.
  • It recognizes that choices and sacrifices can carry real emotional cost.

Tensions to Discuss

  • The film’s supernatural framework treats portal-based mystical forces as the engine of truth and rescue rather than God’s providence.
  • It may encourage children to think of memory as the core of identity, which parents may want to contrast with being known by God in Christ.

Content & Discernment Markers

Occult & Spiritual Content

  • The story begins when Jo and Raissa are transported through a mysterious portal to the fantastical island of Nakali. That portal-and-realm setup places the adventure inside a supernatural system outside biblical teaching, so parents may want to discuss the difference between fantasy magic and the real spiritual hope found in Jesus Christ.
  • The island’s rules appear to include a supernatural cost: the girls may lose the memories of their friendship in order to return home. This gives the fantasy world unusual power over identity and relationships, which is worth discussing with children.

Sexuality & Relationships

  • The central relationship is a close friendship between Jo and Raissa, shaped by affection, loyalty, and fear of separation. Sexual content does not stand out as a notable concern.

Identity Themes

  • A major emotional thread is the possibility that Jo and Raissa could forget each other forever. Because the story ties memory so closely to identity and belonging, parents may want to remind children that a person’s worth rests in being made and known by God, not only in what they remember.
  • The film also carries coming-of-age tension as the friends face life changes and the possibility of going separate ways. That can be a helpful opening for conversations about growing up without making another person the center of identity.

Violence & Intensity

  • The adventure includes fantasy peril tied to being trapped on a strange island and racing to escape before a permanent loss takes place. The tension sounds more suspenseful than graphic, but younger children may still feel the threat.
  • Mild scary moments are likely connected to the portal journey and the dangers of the fantastical setting rather than realistic violence.

Language & Humour

  • Strong language does not stand out here, and there is no notable evidence of profanity, crude jokes, or sexual humor.

Other Content Notes

  • The emotional cost of the story is significant: returning home may require surrendering the memories of an entire friendship. For sensitive children, that loss theme may hit harder than the fantasy peril itself.

Notable Moments

  • Portal to Nakali: Jo and Raissa are suddenly transported through a mysterious portal into the island adventure that drives the story.
  • Memory as the price: The central conflict turns on the possibility that returning home could cost the girls the memories of their friendship.

Discussion Prompts

  • Identity and memory: If someone lost important memories, would that change their value as a person? What does God say makes us precious and known?
    • Biblical guidance: Help children see that identity is deeper than memory. We are created by God and fully known by Him.
    • Scripture: Psalm 139:1-16, Genesis 1:27
  • Friendship and loyalty: What makes a friendship healthy and faithful, and when can fear of losing a friend become too controlling?
    • Biblical guidance: Scripture honors loyal friendship, but it also teaches us to love others without making them our ultimate security.
    • Scripture: Proverbs 17:17, John 15:13
  • Supernatural stories and truth: How is the movie’s portal-and-magic world different from what the Bible teaches about spiritual reality and where our hope should rest?
    • Biblical guidance: Use the film’s fantasy elements to contrast imaginary supernatural systems with the true spiritual hope we have in Jesus Christ.
    • Scripture: Deuteronomy 18:10-12, Colossians 2:8
  • Sacrifice and rescue: What kinds of sacrifices do the characters face, and how is that different from the sacrifice Jesus made for us?
    • Biblical guidance: The story can open a conversation about costly love, while pointing children to Christ’s real and saving sacrifice.
    • Scripture: Romans 5:8, John 15:13
