Fairytales can be seen as formulaic, but these formulas provide the bones for modern writers to fill in as they please; adaptations of classic fairytales are still making bestseller lists and hitting the box office every few months, showing how versatile these classic tales can be, as Lincoln Michel points out over at the Guardian. The nondescript yet vaguely sinister tone of Grimm-style fairytales lend a dark twist to modern interpretations and give writers a surprising amount of creative leeway to make our skin crawl in new ways.
