Not to mention, illegal back ally bot fighting and gambling. Like.. I just feel like there are other Disney Titles that could have been much better examples of the point you were driving.
I think that is, well, simply incorrect to suggest that finding “adult” themes in Frozen or Big Hero 6 would be challenging.
In one you have the tragic loss of parents, being orphaned children, mental health and isolation, etc. And in the other you have the murder of a brother, again orphaned kids taken in by their aunt, a revenge ark and a take over the world villain that is anything but fantasy.
