My regular reader will know that I'm a sucker for most "reality gameshow" experiences. Touch The Truck, Big Brother, The Farm, Celebrities In The Jungle, Back to Reality, I get sucked in by them all. Anything as long as it isn't hosted by Patrick Kielty.
In my (possible quite temporary) opinion Castaway 2007 is the finest of the lot. I'm not so bothered about the weekly BBC1 show to be honest (its mostly stuff I've seen elsewhere), but I love Richard Bacon's Sunday night Castaway Exposed show on BBC3 (Bacon: the most underrated and adaptable presenter on the box, despite his stupid shit-eating grin), I avidly soak up the daily BBC3 show with the wonderful Danny Wallace(in the more casual BBC3 format proving himself to be double the entertainment value that even two Ant's and Dec's would be worth if put together, whatever the hell that means), and I even press my red button every day for the even more casual red-button special episode!
