Have just got back from 2 weeks in UK, where I popped in on BB and agree it is a bit of a freak show, and has been for a few years now. But, in the end even the freaks have a side to them (a soft, or hard underbelly) and it is (or can be) interesting to see them let their guard down and reveal that. Even if they don't, there's always a chance they will. The game (for the viewer) is to try to work out who is genuine or not. To see who is playing the game, and to guess who will be the next one out.
Then there's trying to work out if the voting is fixed.......
