How to Train Your Dragon: The Hidden World

2019

As Hiccup fulfills his dream of creating a peaceful dragon utopia, Toothless’ discovery of an untamed, elusive mate draws the Night Fury away. When danger mounts at home and Hiccup’s reign as village chief is tested, both dragon and rider must make impossible decisions to save their kind.

Ages 8+Source checked

Why this age? PG-rated animated fantasy with frequent action peril, threatening villains, captivity, a character apparently dying, grief, and an emotionally weighty goodbye. Romance is mild and nonsexual. This is guidance, not a safety guarantee; reading level and family context may differ.

What’s in it?

Products & advertising1/5
Why this rating?

Part of a larger franchise with merchandise, but the film itself is not promotional.

Death of a character3/5
Why this rating?

Hiccup's deceased father is mourned, nearly every Night Fury has been killed, and Grimmel is left to die. The dragon farewell is emotionally sad but hopeful.

Graphic injury1/5
Why this rating?

Danger and implied injuries occur, but the supplied plot indicates little or no graphic blood or wound detail.

Strong language1/5
Why this rating?

Very mild, character-appropriate name-calling.

Romance3/5
Why this rating?

Toothless and the Light Fury develop a central romantic bond; Hiccup and Astrid marry. Affection and romance remain gentle and family-friendly.

Frightening scenes3/5
Why this rating?

Dragon hunters, captivity, threatening dragons, traps, drugging, battles, and a dangerous fall create repeated suspense. The colorful animated fantasy style keeps it from feeling intensely frightening.

Alcohol or drugs1/5
Why this rating?

The villain uses a tranquilizing substance on dragons, but recreational substance use is not indicated.

Violence4/5
Why this rating?

Frequent fantasy battles, dragon attacks, traps, captures, chases, explosions, and aerial combat. Violence is action-oriented with limited realistic injury detail.

What’s good in it?

Courage & resilience5/5
Why this rating?

Characters repeatedly face dangerous hunters and personal loss while acting to protect others, with courage framed as cooperation and responsible sacrifice.

Creativity & curiosity4/5
Why this rating?

Inventive dragon technology, flying, imaginative world-building, problem-solving, and the discovery of the Hidden World strongly stimulate imagination.

Diverse representation2/5
Why this rating?

Features a variety of personality types and physical abilities (Hiccup's prosthetic).

Educational value1/5
Why this rating?

Incidental lessons on leadership and diplomacy.

Kindness & empathy4/5
Why this rating?

Rescuing captive dragons, protecting vulnerable creatures, supporting friends, and releasing dragons for their safety make empathy and care central.

Positive messages5/5
Why this rating?

Strong themes support compassion, protecting living beings, responsible leadership, accepting change, cooperation, and letting loved ones go for their safety.

Good role models4/5
Why this rating?

Hiccup, Astrid, Valka, and the riders show loyalty, empathy, leadership, and courage, though they sometimes take risky or impulsive actions.
