What’s in it?

Death of a character4/5
Why this rating?

The protagonist is widowed; her husband was killed by a cat, and Nicodemus and Sullivan die during the conflict.

Graphic injury2/5
Why this rating?

Deaths and injuries are intense but presented in animated, non-graphic fashion, with little explicit blood detail.

Strong language1/5
Why this rating?

Language is very mild; mostly focused on character conflict.

Romance1/5
Why this rating?

Romance is minor: Jeremy meets and falls in love with another crow near the ending.

Frightening scenes4/5
Why this rating?

Threats include a predatory cat, an aggressive guard rat, a mystical owl, thunderstorms, entrapment, and a home sinking into mud.

Alcohol or drugs2/5
Why this rating?

A sedative is secretly put into the cat’s dish to enable the rescue operation; this is plot-driven rather than recreational use.

Violence4/5
Why this rating?

Characters are chased, attacked, drugged, injured, and killed; there are sword and knife fights, sabotage, and danger to a family home.

What’s good in it?

Courage & resilience5/5
Why this rating?

Mrs. Brisby repeatedly faces predators, imprisonment, powerful enemies, and danger to save her child and family.

Creativity & curiosity4/5
Why this rating?

Inventive solutions include rat technology, pulley systems, escape planning, magical objects, and imaginative animal societies.

Diverse representation1/5
Why this rating?

Limited in terms of human representation as the cast is almost entirely animal-based.

Educational value2/5
Why this rating?

The film introduces animal experimentation, technology, problem-solving, and consequences of scientific manipulation, but teaching is incidental.

Kindness & empathy3/5
Why this rating?

Friends and community members provide medicine, guidance, rescue, and practical help, with compassion driving the central mission.

Positive messages4/5
Why this rating?

The story emphasizes protecting family, courage, cooperation, loyalty, resisting tyranny, and seeking independence responsibly.

Good role models4/5
Why this rating?

Mrs. Brisby shows determination and self-sacrifice; allies cooperate to protect her family, while power-hungry behavior has serious consequences.
