I loved this movie, though I must confess I was more impressed with the concept of it than I was with the actual experience of it. Like many others, the hype (I'd also been on the website and my other horror fan friends and I had been discussing it to death) had whipped up a storm of pre-movie anticipation which, to be fair, few movies could possibly stand up to.
I'm completely with you there, Z. I am one of those people for whom the final shot was absolutely chilling. Just thinking about gives me goosebumps. I didn't know about Rustin Parr, but having the shot not on the actual gruesome act resulted in me identifying with the next victim more, if that makes any sense, because I felt as if I was forced to be in his situation--not able to actually witness what is happening, yet still knowing it is inevitable. This engaged my anxiety much more, particularly as my imagination has a tendency to spiral out of control.I could only imagine what was happening to Josh out of the camera's views and that terrified me even more.
