I thought it was really eerie, and didn't realize how much it had affected me until I left the cinema and found I was shaking. I have no problems with the gore and violence of Antichrist (actually, I do, but not in the sense that I can't watch it), I thought Orphan was one of the best movies of the year but with both of those films I was able to watch it distanced from the movie because "it's not real life." Paranormal Activity was far more upsetting and disturbing because the couple in it behaved like any other young couple in a similar situation would. Even the tension between them was well managed.
Maybe I found it scarier because they reminded me a lot of myself and my girlfriend-we're similar ages and the way they reacted to the camera at the beginning is pretty much how she or I would if I brought home a camera one day. Even the way they interacted, in the opening third of the film anyway, was similar to our relationship and that might have made it have an even greater effect on me. Either way, I fond the whole thing pretty unsettling.
Peter Bradshaw wrote a good review in The Guardian that I totally agree with:

It has been some time since I physically jumped at a scary movie. Horror has become a predictable genre and these days, maggoty skulls can leap out of wardrobes all they want, and we merely yawn. But in this film, all it took was one bedroom door to move 12 inches, unaided – just that, nothing else – and I felt like leaping into the arms of the person next to me. And there were moments when I thought I would not just need to change my trousers, but have them professionally incinerated by a biohazard disposal team.
