The story of Hansel and Gretel is notoriously grim -- as are most fairy tales, when you're consulting the source material rather than cheery adaptations -- so a sinister-looking aesthetic to accompany its text only makes sense. Architect-turned-comic artist Lorenzo Mattotti teamed up with Neil Gaiman to retell the fable, and Mattotti's cataclysmic scenes, with violently winding trees and lurking shadows, lend it its rightful eeriness.
The visual style isn't the only amendment to the original. Gaiman's redrawn the characters as well, making the witch less overtly evil, and the children's parents less outright negligent. He even goes so far as to grace the story with a happier ending. See an excerpt of the duo's spooky collaboration below:
