I have to agree, while he may have some medium skills far too much of what he does is fraud and showmanship.
I didn't notice at first when I started to watch Most Haunted but then once I became aware it was quite obvious, every week he was being posessed by grumpy old men. Watchin the Ghost Towns Live event this weekend its the same.
After I heard about the Daily Mirror thing a few weeks back I started looking for info on it and found a skeptics website which had a breakdown of his last GHL event. I was quite suprised by what they pointed out, the link is here if you want to check it out
http://homepage.ntlworld.com/isil.telemnar/Doublexposure/ghost_towns_live.htm If you look on that site theres also mention of Derek running premium rate phone lines.
Im convinced he must have some skill because he does pick up stuff, but the way he sells it just doesnt sit well.
