What they share
Both films are directed by Hiromasa Yonebayashi, and they both carry the cozy, tender mood tags, and they sit in Animation / Family / Fantasy territory. If that's the register that drew you to The Secret World of Arrietty, the second film will land in a comparable space — through a different lens.

What Mary and The Witch's Flower is
Apparently witchy things happen in the countryside. Mary finds a mysterious flower and broom. It all gets rather enchantingly chaotic.
