I think it was setup because a lot of Criss Angel's tricks are staged tricks
Althought most magic is staged someway, I know what you mean...
His Deja Vu (the one where he transports people down the hall), the one where he went through the store glass window, and the one where he pulled the girl apart in the park (just to name 3 for now) were all clearly use of staged 'viewers'.
If he is going to have people pose as average passerbys (a clear lie in all 3 aforementioned tricks) when they aren't, then he loses all credability. Anyone can do that, without the least bit of magical training.
I will not go into details as to how these tricks worked to to not reveal "the secret", but I will say everyone who participated were staged people. Given his tricks would be incredibly impressive had he not had to do it in a 100% controlled environment, it's quite a shame that he would resort to that kind of junk. If you have to hire someone to ooooo and aaaaa at your tricks, then quite frankly, you don't deserve to even be considered a magician because you have no skills whatsoever.
ANYONE can hire some friends and tell them how and when to react. Sorry, but that is not magic. If you can pull off a miracle trick in front of me, then that is considered magic. But the use of camera edits and positioned "bystanders" is a weak way to make a name for yourself
The amount of times he has used pre-positioned actors has caused him to lose all credability as a magician
