I've watched John Edward in his "Crossing Over" performance a number of times. It surely does seem authentic. If it is, the program deserves major network time, at least in competition with the afternoon "my wife is sleeping with my favorite call girl's brother's gay lover" crap. It doesn't seem to fall under the Sci-Fi category. If it is made up stuff, it could be on A&E at least.
I have to admit that the messages from the other side are pretty disappointing, mostly just showing someone in the audience that a dead relative or friend is there ("acknowledging"😉. But it is entertaining, and it gives lots of hope regarding what happens to us when we die.
If Edward is making all of it up, just for money, he deserves to "cross over" himself, right now!
