This is rough movie for a lot of people, but it's an incredibly powerful cinematic experience with an astonishing performance from Emily Watson (who was rightfully nominated for this). Lars Von Trier's movies are always intense and heavygoing, and this one is no exception, but the overall effect is devastating. Watson is a woman with a childlike mental capacity who will do anything to please her husband (Stellan Skarsgard), even if he may not be in his right mind in what he's asking her to do. Set in the bleak hills of Scotland and to a 1970's soundtrack, this may not be for everyone but you should at least try it out and see if works on you the way it did on me.
