It has brainwashed any girl between 2 and 12 so it is damn effective at least. It has some of the most impressive snow and ice effects I have seen in an animated film and the small Norwegian details make make my national heart blossom. I also like that the animals don't talk for once and while going completely bonkers by the tunes as my kid sings them ALL THE TIME it is easy to understand why this one was a success.
The original Snow Queen was a surprisingly feminist story about a peasant girl rescuing her BFF from an evil snow queen who may or may not be in league with Satan. Most of the people who help her are women. Somehow, Disney managed to turn it into a generic Disney princess movie. The animation looks like one of those direct-to-DVD Barbie movies from the 2000s. Just watch the Soviet version instead.
