Based on the book series by the same name, The Sisters Grimm is about the titular sisters moving in with their grandmother after their parents mysteriously disappeared, and facing supernatural peril after supernatural peril.
The animation is decent enough and despiste some clichés (as expected from something based on the definition of fairy tale) the show manages some surprising twists and turns.
A high recommendation.
