YMMV / Donkey Skin

• Nightmare Fuel: It's a story about a young woman threatened with rape by her own father, and her only recourse is running away from home. This makes it (and the complex of similar "father tries to marry his daughter" tales) arguably the darkest of traditional European fairy tales.
• Older Than They Think: The tale is inspired by the legend of Saint Dymphna of Geel, an Irish princess that her pagan father wished to marry. The fairy tale is a version of this story without its original Downer Ending: the Christian Dymphna ran away, but when her father found her, she refused once again to marry him, and he killed her. Also, Dymphna's father's advisors were the ones who advised him to marry her, whereas the advisors in this tale are rightfully horrified when he has the idea and try to sway him off it.
