I thought this was easily one of the most well-made, convincing horror films made in the last decade. No cheap "jump" scares or unnecessary 'warning' music. Straight up docu' style, the actors didn't come across as acting at all & it worked.
This'll be a tough act to follow in my book, but are there any others that're close to this? They don't even have to be in English. They just have to be as subtle & effective as this was.
