Fantasy musical. Originally developed as an adaptation of, but ultimately almost completely disconnected from, Andersen's The Snow Queen (1844).
A witch is born. Her powers are obviously dangerous, very hard to control and religiously stigmatized, so her parents isolate her. She still accedes to the throne of quasi-Norway. The cat is out of the bag in a matter of hours.
A step forward for mainline Disney musicals. The main innovation is the focus on familial love between two women, with men relegated to the sidelines. I also appreciate the almost total disavowal of Andersen's Christianity as it might apply to Elsa's powers. The humour is good: I often chuckled at little details. The genuinely dark parts are also good: The classicist death of the parents occurs almost on screen, and the main dramatic impetus has a suitably unclear internal source. This film would have been excellent if the musical element had been toned down or better integrated, if there had been less royalism, and if Hans had been neither face nor heel. The non-discovery of Elsa's powers before she comes of age is terribly implausible, and her liberated appearance is that of a boring plastic bimbo.
