This is a true tour-de-force that has you gripped to your seat.
It starts of gently, but don't let that lull you into a false sense of security that nothing much is going to happen - it is! And when it does, the tension doesn't let up.
When I saw it the IMDb rating at the time was 8.9, which is very high. All I can say is that it is that high for a very good reason.
Not only is it one of the best thrillers I have ever seen, but the cinematography is stunning. It captures the beauty of the location in such rich tones it is worth watching a second time just to admire the thought has gone into this. But it isn't just the large panoramic shots that are terrific, it is also the smaller sets such as the hotel where George goes for tea, and I don't know whether the director intended the contrast between the cold and clinical chief of police's house and the warmer tones of George's family home, but if they did then that was genius.
If your heart is not racing by the end of the film you're not alive. Awesome!!!
