No sequel is essential, but Frozen 2 makes the argument that, even in the fairy tale land of Disney, they can still be important.

For all its feints and innovations, Frozen II knows its audience inside out, and wants to ensure every last subdivision leaves feeling both seen and satisfied. That’s obviously good business. But it’s also generous, deeply charming filmmaking.

The best things about the first film — the characters and music — once again sing in a frequently dazzling if narratively flawed sequel that’s better at being sensory than sense-making.

In a world where old-timers accuse the youth of being oversensitive snowflakes, Frozen II shows what it means to have one’s heart in the right place.

Like the first film, Frozen II is less a triumph of storytelling than of packaging. It bundles together a bunch of familiar, likable characters and a fresh list of bright, catchy songs, expertly written (by the returning duo of Kristen Anderson-Lopez and Robert Lopez) with an ear toward the Broadway showtunes they will one day inevitably become.
