I saw this last night and was blown away! It starts off a tad slow, but it picks up quick and delivers more than you ask for. All the performances are spot-on, and the entire mood is one of increasing dread. This film is a love-letter to the golden age of radio, and I kept thinking back to the original "War of the Worlds" broadcast. The sense of isolation was intense, and there was just no way to know what was really going on. This is one of the few films that have truly frightened me, and that's hard to do. The gore was minimal, but very well used, the story was solid, and the sheer weirdness of it all pushed this film into my top list. I also enjoyed the fact that the movie trusts its audience to be intelligent. There is no pat explanation to these events, no convenient back-story, and not even a certain ending. What there is, is an incredible experience which should not be missed. This is a literal breath of fresh air in Horror, and it was a joy to behold. Totally worth your time.
