I don't get your point. You're saying it's fake but also calling him a mong. If he was an actor then maybe he acted like a mong. On the flip side if it's fake, they'd have made sure the actor wore the proper attire.
I don't see what the issue was, all he did was take a loser and give him confidence by subliminal methods. People watching saying 'OMG FAKE' are implying DB has done something amazing, whereas I found it quite dull, nowhere near as impressive as The Heist and other stuff he's done.
FYI I'm pretty sure parts of the show were embellished, edited a certain way or re-shot, like most shows, but don'tthink the whole thing was a set up, what'd be the point? Nowhere near as impressive as predicting the lottery or playing Russian roulette (both of which were fake, at least the former)
The guy involved, Matt, I was just saying was hilarious. If, as I suspect, he was an actor, it wouldn't surprise me if they made him dress like that to make it all the more believable that this bloke was that dull.
I'm fairly sure it was all fake as hell, the holes you can pick in it are obscene. The bit with the alligator, at one point it starts pissing it down while Derren is speaking to him, yet only Derren gets wet, all the cut backs to Matt show him dry as a bone. And as they walked off with the shot above them after that, they're both dry.
No simulator has graphics convincing enough to be reality.
No-one, on hearing a voice in their room, goes out to the garden.
No-one randomly walks into a house and watches a guys TV.
I guess the whole thing took the suspension of disbelief well beyond where it holds up. And neither, as you say, was it interesting, at all. He's done so much better than this, even the more blatently fake stuff (the zombie game) was at least interesting, this was almost like he wasn't trying.
