You almost don't want to write too much in case you spoil the film for others! It is all in Danish but don't let that put you off, after five minutes you forget you're reading subtitles. The film increases the tension superbly and whilst disturbing in places it is absolutely fascinating and riveting. Hadn't heard of the film prior to watching and held no expectations but found myself being sucked in and that the film held my attention for its duration. At 1hr 25min running time it is a great antidote to 3hour Hollywood films that are overly long and full of their own importance.
Short, sharp and incredibly well acted, you shouldn't be disappointed.
5/5
