Marco Tempest hasn't just turned up out of the blue, he's been around for a while; the first time I saw him on TV was on the Eurodisney magic special a good ten years ago, at that time he had a video screen routine that while it was more a piece of choreography than magic per say, was definitely entertaining and well executed. In short, the hi-tech multimedia thing has always been Marco Tempest's character. He also seems an amiable chap and has posted a short but useful article on doing magic on camera at

As for the series itself, while the premise is patently ridiculous with the capacity for humourless pretention that the Americans seem to have a flair for in this sort of thing, Marco himself comes across as a likeable eccentric who often brings something extra to each effect and certainly does the art no harm at all.
An effect of the street magic trend is that many standard effects have become overexposed overnight; can there be anyone with a TV now who has not seen Pen Thru Anything at least four times? But then there's the way Fay Presto put it when asked in a TV interview whether her tricks were her own or passed around within the Magic Circle, she compared magic tricks to songs; some you write yourself, some you have written for you and others are common standards that you make your own. This is as apt a way of putting it as I've ever come across.
The other thing I tried to point out in the "reputation makers" discussion is that many of the actual bona fide reputation makers were already old and well worn effects before the performers concerned found ways to make them their own. It's easy to miss the point of why they made reputations; people have been doing Russian Roulette for years, it's a stock mentalism effect, but it took Derren Brown to base an entire special around building up that one effect, getting in every newspaper in the land and becoming a household name in the process. Now if you ask any British non-magi (I hate the word "layman" so avoid using it where I can, but that's for another discussion) about Russian Roulette, chances are Derren's name will be mentioned.
