Fake...
Having studied some paranormal in the past, and being familiar with the history of the Dibbuk Box (aka dybbuk box), I can pretty much say that this show is either scripted or just plain fake.
I've seen their previous shows, those are "entertainment" if nothing else, but none feel more forced and scripted than this. Notice when "Kevin" went into the basement with the Dibbuk Box, when he was supposedly reciting that rhyme (in a "different voice"), that he was the whole time behind a pole, or his head and face were completely engulfed in shadow, you never saw his mouth moving (it clearly was NOT his voice, but the voice of an actor).
It still shocks me how many Americans will believe in this crap...
