I was surprised at how unimpressive this movie is.
For me, just the fact that the mediums controlled the entire thing while people just sat around and watched is highly suspicious. This was done in a controlled environment arranged by the mediums.
How about doing this in a research facility where these mediums can come in and sit in a room arranged by researchers? Surely these spirits are cooperative as they were, would be ok with this.
I have never see a medium who seemed truly convincing. They usually just play the probability game, where they will look at someone and say something like :
"oh i see someone in your life that passed away. ummmm his name begins with a C " .
Never have i seen a medium truly go out on a limb and say something specific while being accurate.
