Astonishing frightening movie. Psicilogically challenge a next generation of spectators to be afraid and to think at the same time. An invitation to horror, at the level of Ringu, or Dark Waters. Give this guys some money, and they will blow your mind. The lightning, the sound, it all contributes to a clime of eternal nightmare. The cast is worth of applause's. Genuine fear is seen in the faces. Genuine threat is also display. A new trademark of horror. Forget Wes Craven, meet his child's. Do bot blink, or you'll be missing a part of the psychological puzzle. Right from the star we are into in the several lines of action. There are many, and our standard movie spectator brain gets into a tsunami of information and dropped-by images, that doesn't seem to be linked in any case. Every time you try to think, your chest is assented with a new horror. Do not Confuse, this is not a Roib Zombie movie, this Night Shymalan with guts, this Craven with taste, this is Carpenter with new ideas. This is new horror, from attenuating to the world. Excellent choice for a horrible night.
