If your a fan of M. Night's work you won't be disappointed. It has underlying uneasiness that builds throughout. Even though it starts with the feel of a found footage flick it quickly telegraphs that it's more. There are some genuine scares and an unrelenting series of events that have the hair standing on the back of your neck. The child actors are good and thoroughly believable. Well worth a look but if you're more into the slasher style this may not be for you.
