Gimme this over Lord of the Rings any day.
Excellent suspense, great performances, gorgeous cinematography and effective sound design. Unfortunately this is all bogged down by some pretty cliche Hollywood horror missteps; mainly numerous gaping plot-holes and over-the-top CG monsters that really took me out of the movie. In saying that, I can definitely understand the hype and there's no doubt this is a well-crafted film with a solid premise. Overall a fairly enjoyable mainstream horror experience.
