My personal take on it
I've known about Tony Robins for quite a few years, and it's quite apparent what a communication genius he truly is. He is the epitome of the perfect public speaker, he is fast, articulated, has a deep voice that he perfectly projects to the audience, knows how to captivate and keep a high energy speak for HOURS. Few have the skills to pull that off.
He has some very interesting insights on motivation, and his lectures on the subject are fascinating. I'd be very interested in attending a 1 or 2 hour lecture from him on that subject matter (or perhaps about leadership skills). His coaching technique is far from being "fraudulent", albeit not being anything new.
HOWEVER, this particular 6 day course really feels a bit off to me. It's too vague (what is it about? fixing problems? achieving dreams?), it's too sparse and unfocused, and doesn't quite seem to be a perfect fit for everyone, unless having that empowered motivational "buzz" for a few days is what you're looking for. The documentary focused only on the "miraculous" testimonial parts, ignoring there's hours and hours of lecturing and theory material presented that may be a little bit more interesting for those who are truly expecting to learn something - and not witness miracle cures like some loud, fast talking televangelist preacher. It was like a turbo-mode fast paced therapy session (all he did is pretty much go through the motions of a therapy session) in front of THOUSANDS of people. It looks like borderline brain washing, and, judging by the way this documentary was edited, it might have been their original idea - to show two sides of the whole thing (kinda like "Jesus Camp" did). What is the line that separate religious charismatic preaching and motivational speaking?
While I'd gladly attend a short seminar or talk by Tony Robbins, I'd not put up 5 grand on that Destiny 6 day seminar. Of course a lot of content was missing from the documentary (partially because I doubt Tony Robbins wished to have it all out there, he wants people to pay), but the little I saw did not convince me.
"You keep him in here, and make sure HE doesn't leave!"
