What’s in it?

Products & advertising1/5
Why this rating?

A fictional restaurant-arcade and its field trip appear briefly, without a sustained push toward buying products.

Strong language3/5
Why this rating?

Frequent silly names, embarrassing name changes, ridicule, and schoolyard-style insults are central to the comedy.

Frightening scenes2/5
Why this rating?

Children and a school face fantastical danger, shrinking, pursuit, and hostage situations, but the tone remains comic.

Violence2/5
Why this rating?

Cartoonish chase scenes, inventions, hostage-taking, and defeat of the villain create peril, but violence is exaggerated and non-realistic.

What’s good in it?

Courage & resilience3/5
Why this rating?

The protagonists and Captain Underpants face dangerous situations and work to rescue others and restore the school.

Creativity & curiosity4/5
Why this rating?

Comic-making, inventive pranks, imaginative transformations, and problem-solving with machines are central to the adventure.

Diverse representation1/5
Why this rating?

The fictional country of New Swissland broadens the setting slightly, but substantial, well-developed human diversity is not evident from the available material.

Educational value2/5
Why this rating?

Inventions, shrinking, enlarging, and a school setting add light science-related ideas, but teaching is not the main purpose.

Kindness & empathy1/5
Why this rating?

The professor initially hopes children are kind, but much of the plot involves mockery and retaliation; cooperation appears mainly during the rescue.

Positive messages2/5
Why this rating?

Creativity, friendship, and bravery matter, but pranks and ridicule are also used for humor and revenge.

Good role models2/5
Why this rating?

George and Harold are inventive and loyal but frequently disobey, prank adults, and seek revenge; consequences are comic rather than strongly corrective.
