The Signal is more than just a horror show about technology going out of control, it's also about the seductiveness of techno-chaos. The mysterious transmission that takes over electronic devices at midnight on New Year's Eve turns every other person into a murderous psychopath, but also seems to dispense ecstasy, judging from this newly released trailer. The final shot, of the main female character clutching the headphones to her bruised head and swaying with rapture, is pretty haunting. [ShockTillYouDrop]
