I've watched the film and I tell you now, it's not something you can unsee or forget. I had goosebumps on my arms and shivers running up and down my spine the entire film. It isn't scary, but more freaky and unnerving. I would recommend it, if you were into that.
My friends are also trying to make me see the second one and I told them flat out 'no'. There is no way I'm seeing the second one unless I drunk and bound in place.
