I don't get how you can say Derren Brown is boring and repetitive. He hasn't done the same trick twice in the 3/4 years he's been broadcasting and every show prior to these DIY type programs have been excellent. I don't think there's one trick I've seen that I've ever thought, "Oh that was ridiculous" or "boring", they've always been rather mind-blowing.
I'm also a little disappointed at the lottery episode and the stick-to-your-chair episode didn't work for anyone I know, but there are perfectly good explanations why. It was obvious he wasn't going to explain his method on the lottery show, otherwise everyone would be trying it, and he already had to gain clearance from Camelot before he started, so I doubt they would really have given him clearance if he was then going to tell all. The STYC episode can be explained mainly by the environment you are in and the fact you are not in optimal conditions. Regardless of this though, the other tricks he's done on those two shows were excellent. Especially the undercover tramp one in today's, where a random guy gave all his and money and even his shoes to him. I have a friend who's seen him live here in Nottingham and some of the tricks he performed live were unexplainable and were clearly unplanned (e.g. he threw a toy out to the audience, which selected people at random to participate). The guy is beyond simple misdirection, psychology and magic tricks. He's superb and a lot of his tricks are refreshing, simply because they haven't been done before in public and under such conditions.
