A woman finds a family, including a baby, frozen (to death?) in their home (caused by the sudden onslaught of winter)
It appears a creature is about to be butchered alive in two different scenes in the monsters kitchen. (the cook is swings a machete repeatedly into the table with the humanoid creature on it, and the creature reacts to each swing, but appears to be undamaged?) The short of it is, it is apparent they butcher people alive and cook them up and eat them in the kitchen by this and various other scenes.
The character Meg Mucklebones may be frightening for very young children.
Scenes with the lord of darkness can be scary for young viewers. A woman readies to behead a unicorn (she doesn't). The creatures are all gross and scary looking. A man is threatened by (and later beheads) a hideous creature. A pig like man is going to eat some other characters (he doesn't, but he does put them in a large cooking pot). Some scenes under violence can be considered frightening/intense, suspenseful music generally plays throughout these scenes. Some bizarre/scary images, the demonic Darkness may appear frightening to some children.
