Jumpscares are common throughout the film and are fairly common.
There is a scene where a character transforms into alternate disguises, in which their head and neck shift and convulse. Cracking sounds can be heard throughout the conversion, and it goes on for some time. Viewers may find this scene uncomfortable and disturbing.
The movie has a very children's book feel, but it still delves into rather strange supernatural images and subject matter.
This movie is frightening and intense to varying degrees throughout. Creepy
The first half of the movie the scary scenes are humorous and light however they get drastically more creepy and scary in the second half. It is quite a drastic change and can very very frightful for children. At that point even the humor doesn't lighten the fearfulness of the movie.
