I am really pleasantly surprised! This Swedish movie is really simple and plain haunted house story with focus on few characters and their experience with horror. The best thing is simplicity and minimalism - everything happens in and outside house without any explanation why scary events happens which is great and original approach that simply put viewer in the same line with characters on screen. Also, actions of characters tend to be realistic as it possible - with all bad, stupid and good moves without silly heroic and/or cold approach to mysterious events in the house. Very different from other haunted house movies. Also, lack of gore and usage of light, shadows and sound instead over the top FX to produce horrific atmosphere is fantastic approach and works amazing! Even awfully bad English dubbing in the version I watched, occasionally lame acting and silly ending can't reduce real creepiness of scary scenes.
Very different view of pretty exploited theme with situations and actions that are the closest to reality if this would happen to some real family in the real world.
