So many bad reviews...
...but I thought this was a really good, genuinely creepy film. Clearly not an Oscar winner but I thoroughly enjoyed watching it and freely admit to getting a little spooked with the anticipation and build up of the 'scare' scenes. I've sat through films like the 'Paranormal Activity' franchise and although they had moments that made me jump they just weren't creepy or scary at all.
All told I would definately recommend this movie...although judging by the majority of reviews and posts I would seem to be in the minority.
