"Sauna" is about two Finnish soldier brothers assigned to map the new border with Russia in 1595.They come across a mysterious cement sauna in the middle of a swamp.When people enter it,they are forced to confront the sins of their past."Sauna" is an eerie and lyrical horror film with slow-moving pace and plenty of subtle creepiness.The director of it Antti-Jussi Annila said in an interview:"Old Finnish people,before Christianity,believed that the sauna was the place to wash your sins away so you can go on living without the bad things you have done",so basically the main themes of "Sauna" are redemption and damnation.The film includes a haunting image of a ghostly girl with face drowned in filth,who was left to die locked away in a cellar by one of the brothers."Sauna" is a perfect example of existentialist horror with drained-out look.7 out of 10.
