A good film, but it freaked out my younger sister

Rating: 7/10 (23 June 2019)

This film had a very interesting storyline, and I think that the style of animation allowed the concept of the parallel world to be more effective. I did enjoy this film, but I found it creepy and unnerving, and my younger sister was actually disturbed and freaked out by it. I was kind of concerned that it is only rated a PG, because although there aren't any adult themes, it is almost like a horror movie in animation, and I don't think it's particularly suitable for kids below 10 or 12.
