Yes, it's in the vein of repetitive 'found footage' movies, but this is highly intelligent and way above average - Another notch up on the creepiness scale, gentle storytelling and solid character building. A WTF moment about 'knocking on the door' and an unexpected (but very welcome and promising) twist at the end. This is a really good mystery that is reluctant to be unravelled... Absolutely love it so far!
