This is a great little film, with some genuinely creepy moments. Yes it is fairly predictable and not exactly original. However it makes up for its unoriginality with good acting and competant directing. The close-up of Ulf Pilgaard's (Inspector Wörmer) face when he realises that Sofie Gråbøl (Kalinka) was at the murder scene is both funny and terrifying as he weighs up his options. Anyway it is far superior to the US remake (it seems as though people are split on this: generally Americans like the remake, Europeans like the original). Stick with the original, 7/10.
