A not so great movie. The movie reminds me a lot of paranormal activity. The way is filmed and all the rest. Something happen always after a certain time, exactly like paranormal activity. Now, during the movie the kids say that they don't have signal in the house, however they use Skype which requires an internet connection. You can clearly see a blue cable coming out from the laptop.These cables are used to hook up a desktop/laptop to a router. Now if you do have a router you can just use your mobile over the router. The movie is very flat, from the trailers I was expecting more that's the reason I decided to go to the cinema to watch this movie. Some parts of the movie just made me laugh, I don't know if that was the intent of the director or if just happens. The end of the movie has a twist that I didn't predict that is the reason I decided to give a better rate. Without the twist the movie would have been more flat, and definitely worth only 1 star. All in all I would say the movie is not worth the ticket price.
