Oo yeh i really enjoyed The Mole. There was a series on another channel.. i think it was challenge or living tv and there was an American series but after that i have seen no more.
I remember it yeah its was a brilliant idea, especially the way the viewer was given cryptic clues as to who the mole was. eg in series 2 the name of the mole was spelt out by the first letter of the first word the presenter said in each episode. class. channel 5 seem to be god at the reality stuff. Bring back the farm too.
If i remember correctly the reason there was only 1 series was because the viewing figures for the series were not that great.So another series wasn't commisioned.
