Saw this today with wife and 19yr old son, we were literally the only people in the theatre. We all thought it was marvellous. The tension is constant throughout and Russell Crowe is superb. I generally don't find horror movies scary as I know it's all BS and I've seen every trick over the years, but I was squirming in my seat expecting the worst at every point. The worst didn't necessarily happen, but the anticipation was off the scale.
