Dogville
I watched this in three days, three sittings; and day by day, I slowly became obsessed with it. When the movie ended, I felt the same as when you finish a great novel and put it on your shelf proudly. I loved this film. Everyone should watch this before they die. It is both unique and realistic at the same time. It reflects human nature, evil in society. A popular review for this movie was "this is somehow both the most frustrating and most satisfying movie ever made". I completely agree. I felt so much watching this.
