I didn't see this live because...well, I live in the USA, but I do have it on DVD. I thought it was pretty effective. Until the end when the ghost invades the TV studio (I think I'm remembering that correctly?).
But that's the problem with pretty much all these "real" footage style movies, the endings are always lacking. Paranormal Activity
sees to have pulled it off the best, but still that last lunge at the camera is pretty cheesy.
