The point is Frozen has had unprecedented success in this field. Its not like Cars where we got the first talking cars that little boys could attach character attributes to. Princesses are a dime a dozen. The Princess and the Frog hasnt had the same success in selling soundtracks, dolls, clothes, toys, plush, etc. Why? Is it because it had more competition at the box office? Cant be, because it was purposefully released to avoud going head to head with Alvin and the Chipmunks. All things considered, Frozen is a good movie with good characters and a solid story and an above-average soundtrack that isnt restrictive to just one demographic...that is where the bulk of its success has come from. Sure, competition always has something to do with a films success, but not to that extreme degree.
