Sauna (or Evil Sins) is a very well done historic dramathriller mixed with supernatural horror elements and is in my opinion, one of the best films my country has to offer. It has great actors, interesting story and the mood is excellent which is important and usually missing from most modern horrors. The mood and story are what drives the film forward, not jump scares and gore. The story doesn't hold your hand and not everything is plainly explained. If you like older, creepy, mood-driven horror and like dark, nordic films/shows and stories, watch this.
