The world it depicts is one were belief in the devil and witchcraft is woven into the fabric of the society. When one family is banished from the settlement they set up in the woods. The father William played by Ralph Ineson leads the family to set up home on the edge of the woods. As you know in horror films you dare not go in the woods. First a baby is snatched and taken into the woods. This triggers the family to disintegrate with each suspecting each other of being a witch. Most films dealing with witch craft have the obligatory burning scene but in this film a witch is seen not wholly as a victim but as empowering.
The actor Anya Taylor-Joy who plays Thomasin the daughter who is becoming a women is at the centre of this film. Her performance is brilliant and along with the rest of the cast they deliver the period lines with such power you are engrossed from start to finish. The film has recognisable influences from The Company of Wolves, Witchfinder General and Barry Lyndon but it takes all these on to create something new and lasting.
