From NetFlix:

In this fairy tale for adults, 10-year-old Ofelia (Ivana Baquero) stumbles on a decaying labyrinth guarded by Pan (Doug Jones), an ancient satyr who claims to know her destiny. With a new home, a new stepfather (Sergi Lopez) — a Fascist officer in the pro-Franco army — and a new sibling on the way, nothing is familiar to Ofelia in this multiple Oscar-winning tale set in 1944 Spain from director Guillermo del Toro.

In “1001 Films to See Before You Die”, this film is recommended as probably the best film by Mexican directory Guillermo del Toro. The film has a split personality: half is the suffering and torture due to Ofilia’s stepfather who is a bitter and twisted member of General Franco’s fascist army; the other half is the fantasy world to which Ofilia escapes in order to get away from the ugly realities. So, yes, there is violence and some torture. And also there are some memorable fantastic special effects scenes. Not for children.
