Save yourself the 1/2 hour to hour this is on by finding something else to watch. This should never be portrayed as reality. It is anything but. The producers should be ashamed of themselves for ruining their resume with this garbage. It is a complete waste! They do the weakest things to "envoke" spirits. Maybe a 2 second blurb that will make you want to laugh- although they are suppose to be serious. It doesn't even come across as serious.
As for the episode where Nathan "cuts" himself, they cut it real fast, then flash back where some colored stuff is on his arm, but it- to me- does not look anything like blood. Then when he is "cleaning it up" there appears to be no cut.
They yell and freak out and claim things happen yet you see absolutely nothing. All this show is going to do is to teach kids who are followers to vandalize and harm themselves in an attempt to reach a spirit. It is not a very good example. However, once they get sued for that, they might wake up.
I sincerely hope A&E does not allow this trash to continue to poison the channel. It IS seriously that bad.
