The damsel is still doing the rescuing, The snow queen in this film is still Elsa, they did this because disney has tried believe it or not to adapt this film since about 2002. Each time to no avail, they couldn't get the story to work or make it interesting for audiences. The original tale had gerda crying on everything to heal or fix it, talk about new wave feminism
and the snow queen in the old tale isn't even necessarily evil. She takes kai away for saying that he will burn her on the stove, after that she just kind of lets him chill in her castle. Elements were discarded because they didn't work if you don't believe me give this article a read

As for elsa being a princess that isn't even in the film, she is actually the snow queen and the queen of arendelle. The only people calling her a princess is the Disney princess line which is for marketing but in the story of this film she is a Queen. She is also one of the main characters, the name was changed not because the story no longer involves the snow queen, but because marketing dictated that tangled was a success with the name change, so they did the same to frozen. Also almost all fairy tales involve children, and disney has more or less made them adults or older in about each film so nothing new there. I think you should honestly see the film before judging it so quickly. And if you are mad the source material isn't there I reccomend you read some grimm fairy tales or Hans christen Andersen original tales, you'll find ariel's fate should have been a bit more, well, bubbly. I have faith in Disney animation they don't just shelve out garbage (planes doesn't count that is disney toon studios.)
