Derren Brown, I don't think so...

A few years ago Derren Brown produced some really excellent TV and of course originally studied NLP with Richard Bandler in 1997 at a McKenna Breen London training. I attended an invite only TV programme in 2006 for C4 and was pretty impressed. Of course a lot of what he does has nothing to do with NLP (a common misconception voiced on many newsgroups...) but he does use some NLP techniques.

Then in recent years the TV shows became more and more sensational and quite frankly IMO quite irresponsible, culminating with him training people to rob an armoured van. Then in his last book he berates NLP and has in my opinion become a bit of a pratt.

Just a personal view of course...
