Big brother bombed. Brutal. Though when you have weeks of crap filler shows and repeats you can’t expect miracles or even decent ratings.
Hi Sandy – look, over half a million viewers isn’t great, I agree, but it has hardly bombed. The two shows it is up against commercially are high performers so it was always going to be tough. The real measure will be how many people have hung un for next week (and how many are watching online, which for shows like this, carry much more weight).
