Convinced they'd be better off raising themselves, the Willoughby children hatch a sneaky plan to send their selfish parents on vacation. The siblings then embark on their own high-flying adventure to find the true meaning of family.
Loved the animation and the fresh approach to complex family dynamics. Big glaring issue is how the rag on Child Protctive Services in the same old boring trope of souless robots out to sequester children. These people are an integral part to protecting our society's most vulnerable from the very people who should have be providing a loving and caring home but neglect to do so. Hey Netflix, how bout some positive examples for these incredible and hard working heroes next time eh?
