I'm a tremendous fan of simplicity in my scares. I have no use for flash and gore and in-my-face bogus chills and thrills.
Oren has taken the "found footage" premise of horror film making and has blown the rest clear out of the water!
Brilliantly done, and terrific at staying with you after the film is over. I still catch a chill from time to time pondering the movie and it's been almost a full week since my screening.
Highly recommended, BUT...if you have not yet watched the trailer, DO NOT WATCH IT!!! The primary trailer gives too much away, in my opinion. Just see the film and prepare to be freaked.
