The story is interesting, but with a very bad flaw: the snow thickness is really a joke, very easy to break and that decision to just stay there, in this case, doesn't make any sense! It's hard to understand the decision-making throughout the movie, and that makes it much less realistic than someone looking for a real story might expect. Also, it's irritating that when she managed to be able to call someone, she reaches daddy basically to scream (!!). The idea was nice, I enjoy this type of movie but, in this case, it seems it wasn't so well thought. It has some nice points as well, regarding their relationship, despite her personality is annoying and irritating.
