What is it? Never heard of it. I hardly watch any terrestial TV at all anymore.
Is it related to the gameshow Wipeout that used to be on BBC, with Paul Daniels!
Nope - try to think of it more as Takeshi's Castle mixed with Gladiators and you're sort of getting close. I found it quite enjoyable, and certainly better than watching a bunch of orange b list celebrities mincing round a dance floor for hour after interminable hour. I think if they had gone more over to the Takeshi's castle format and not concentrated quite so much on trying to keep them safe it would have been a lot better.
I think the Danish version of this is filmed at the same place.
