Modern cinema has discovered that the blended family isn’t a problem to be solved. It’s a collision of loyalties—and that collision makes for extraordinary drama. The defining trait of today’s blended family narratives is the presence of absence. Someone is missing: a biological parent who died, left, or was pushed out. That missing person becomes a character in every scene they don’t occupy.

For decades, cinema told us a simple lie about blended families: that love would conquer all by the third act. The step-parent would try too hard, the child would rebel, and after one tearful apology in the rain, the new unit would glide into a Norman Rockwell tableau.

The old Hollywood ending was a wedding. The new Hollywood ending is a quiet Wednesday night where everyone eats separate meals at the same table, and no one yells.
