It's a movie that is appealing for those who really like the genre but if you don't than you won't like it. I'd say 90% of the criticism for this movie is that they are "copying Frozen" which is untrue because both movies are taking from the Snow Queen fairy tale.

That isn't to say there aren't problems. There definitely are. I think this will be a case by case thing and you should definitely see it if your interested.
