If you loved Der Junge und das Biest, try Mirai - Das Mädchen aus der Zukunft
Eine Brücke zwischen einem Film, den du schon gesehen hast, und einem, den kaum jemand kennt. Das teilen sie, und was der zweite macht, was der erste nicht macht.

Der Junge und das Biest

Mirai - Das Mädchen aus der Zukunft
Was sie teilen
Both films are directed by Mamoru Hosoda, and they both carry the bittersweet, tender mood tags, and they sit in Adventure / Animation / Drama / Family / Fantasy territory. If that's the register that drew you to Der Junge und das Biest, the second film will land in a comparable space — through a different lens.
What Mirai - Das Mädchen aus der Zukunft is
One imagines that someone, somewhere, thought a cartoon brat was overdue. Kun, a spoiled four-year-old, struggles to adjust when his parents bring home his baby sister, Mirai. It is a truth universally acknowledged that children's movies benefit from some time-travel shenanigans.
