I liked the movie. It was not too frightening and seemed to have a different approach rather than normal apocalyptic movies involving boring zombies and aliens. In this case it's something new that these invaders are doing, making people kill themselves and the creatures are themselves a mystery which builds up some suspense. And the concept of blindfolds is good too, it's fighting an unseen enemy. Overall it's a change from normal horror and apocalyptic movies though I haven't seen a lot of them but this surely holds a place.
