...but in the end you realize this is something you'll only watch once or perhaps twice. It's a perfect cinema experience however.

The sound work works really well in a theater. There is clearly a very eager and talented sound designer and editor responsible for creating most of the tension. Every single creak and footstep is perfectly placed for the best scares. The plot is the "weakest" part, but it's nothing you'll care about. The best thing is that it mercifully steers clear of all "jump" scenes we know and hate from American scary movies.

After the first act, lightning starts to come in more and more and almost replaces sound as the tension-maker. This is also done extremely well. Actually, this is probably one of the most well- made horror movies in a long time. Everything plays out perfectly; lightning, sound, camera-work(modern, but not annoyingly so) editing and cinematography.

Definitely worth watching for the technical aspects alone, but more so for the tension and the scares.
