Perhaps the most significant development is the blurring of lines between biological family and "found family." Modern films, including many animated features, often focus on creating a family unit based on love and choice rather than just blood ties.
And for audiences navigating their own step-relationships, custody schedules, and chosen bonds, seeing that question asked honestly on screen isn’t just entertainment. It’s a lifeline.
