I haven't watched any other film by Bornedal(including the American remake, which I understand is inferior to this), but he certainly nailed this one. From start to finish, this establishes and maintains an atmosphere and crafts a tension so thick, you *can't* cut it with a knife, you'd need a razor-blade. The editing and cinematography, with only a handful of exceptions, are inspired, using light and darkness immensely well, and utterly terrifying the audience. This is marvelously well-shot. The plot is excellent, and the twist is unexpected and has a relatively subtle, yet nicely effective reveal. Granted, when you think it all through, you do have to accept one or two details that strain credulity. Still, this is exciting and creepy whenever it attempts to be, and the relatable story and credible, well-developed, human characters are the driving force of the movie. Inbetween the sequences of suspense - to keep it from overstimulating the audience - there is humor, and every joke and gag are funny, none fall flat or try too hard. The acting is impeccable, every performance is spot-on. While there are jump-scares, most of the build-up pays off, big time. The music is excellent, and contains a good bit of rock, as well as a cue that they must have composed with Psycho in mind. There is a lot of disturbing content, some sexuality(including in dialog), brief nudity and a little bloody violence in this. The DVD comes with a well-done half-hour long behind-the-scenes featurette that covers the majority of the areas of production, and the theatrical trailer. I recommend this to every fan of horror. 8/10
