It's pretty faithful to the standard Grimm story, as far as I remember. Not a great story, but not really the opposite of something children should be taught. The pedophile/necrophile prince throws up some red flags, and murder via boogie isn't a common thing lately, but I'm pretty sure nobody is advocating to their children that they "be more like Snow White" so it's more about how the story is viewed today in context.

Be really pretty, and everybody will take care of you even if you're an idiot.
