I have been watching their show for about 6 years now. This documentary before their tv show is the best and still scares me till today. Whether you are a skeptic or not, you will get scared sh*tless. Their reactions scared me too, like they are crying for help to get out of that place. I know even though you don't believe because you haven't been experienced something like this, even myself I don't. But, After watching this documentary, made me believe that they are real. After this documentary, they've been all over the news that saying they proved it. Remember, Science can't explain everything, We don't know what's the fact and the truth. We don't know anything why do they exists in the first place. This documentary is the most scariest documentary that I have watched, better than the true-story Horror Films today. Give this a shot, whether you are a believer or a non-believer. For me, It's entertaining, and it's scary as hell.
