Yes, well, the Disney versions often take away parts that were the most meaninful too.
Every mom becomes a step-mom, because, you know, we can't portray a mother as something evil
But many of these stories in the end talk of the generational struggle, how people must "fight" against their own parents when they grow up into the people they really are.
Or how they turned the seven men of Snow White into dwarfs, for a comical release.
Or the whole end of the Mermaid story, which was so sad but also so good. No girls, don't leave everything you have, don't abandon your friends and family to run after a man who won't even show any sign of commitment.
