Happiness Charge Precure! the Movie: Ballerina of the Doll Kingdom

Pretty Guardian Sailor Moon Eternal the Movie Part 1
What they share
Both films are directed by Chiaki Kon, and they both carry the playful mood tag, and they sit in Action / Animation / Fantasy territory. If that's the register that drew you to Happiness Charge Precure! the Movie: Ballerina of the Doll Kingdom, the second film will land in a comparable space — through a different lens.
What Pretty Guardian Sailor Moon Eternal the Movie Part 1 is
You sense a dark eclipse over Tokyo. The Sailor Guardians reunite as a circus arrives, spreading nightmares. But the mysterious Dead Moon Circus seeks to scatter darkness and seize a sacred power. Kon focuses on character arcs, letting the animation recall classic shojo manga. It lingers.
