Wow. Just watched Paranormal Activity and found it genuinely scary. First time in years I can remember being scared by a horror. I even found myself getting anxious and short of breath every time a night time scene started.
To a large extent, horrors just stopped being scary for me after I had stopped believing in absolutely anything supernatural, including God and The Devil and many underlying notions of that type that give horrors some grounding. I heard mixed feelings about it on the Kermode podcast with some people finding it really scary and others who didn’t.
I’ve only seen the trailer below for the first time which probably builds it up a bit too much. But it really hit a bone with me for some reason. Maybe it helps to watch it on your own in the dark in the right frame of mind. That shaky camera stuff really works for me too. If you found Blair Witch at all scary, you’ll get a kick out of this.
