At the end of the day, the BB3 housemates were subjected to different conditions than the BB2 housemates. Who knows how they would have come across had the situation been different. And last year, Helen, who became my favourite at the end, could have gone after two weeks if people at home were not so worried about Penny's sanity! Then "Helen and Paul" would not have happened.
If we want BB4 to be better, we cannot predict how the contestants will behave as much as we would like. So make the conditions as follows:
1. No divide
2. Sensible budgets - forces them to eat together by not allowing them to buy too much, and keeps the boozing in proportion.
3. Team tasks. Get people co-operating. Make nominations really painful!
Then we have a chance.
Can't see it though, they want sex bitching and scandal because that brings in the dosh.
