Well, I am proud to say that H.C. Andersen was danish (as am I, in case you didn't read that in the OP). Sure, he was from Fyn, which is like the butthole of Denmark, but still...
Honestly, The LIttle Mermaid, or Den Lille Havfrue as it is in original danish, is a horrible story. At least the original one by H.C.Andersen. In fact, most of H.C. Andersen's stories were far from suited for children. The man was a real pervert. Snedronningen, uhh, I mean, "The Snow Queen" as the original title for the H.C. Andersen story that Frozen is based on, is actually far from the same.
Also, several of the "Silly Symphony" mini cartoons back from ... way back, are actually based on H.C. Andersen fairy tales. Like "The Ugly Duckling", "The Little Match Girl" and so on. There's some stuff with the Tin Soldier snuck into several of the shorts as well, but it doesn't matter.
I was forced to analyse so many of H.C. Andersen's tales that I've grown a bit... irked, by them.
Also, by "Nordic culture", what exactly do you mean? Viking stuff? Nordic Mythology? I'm kinda Nordic (not "kinda"... I am), so I really don't know what is considered Nordic culture around the world.
