What's The Deal With Tony Robbins?

When I started working on this Tony Robbins documentary I noticed the same comments about him being a scammer coming up over and over again. But then there were the others, regular people having transformative experiences at his seminars turning their lives around.

So is he the saviour many people desperately need, or one of the greatest scammer the world has even seen?
