I don't think it's dead weight. It's doing well in the demos and that's what any station and its advertisers want. People look at ratings numbers and say oh, it's doing so badly but it's in a later time slot and is performing just as well as last season so far in what really counts: the demos. All the complaints people are making this season are the same ones people were making this time last year at the same time.... almost down to the last detail. And all the "it won't be back" people were proven wrong again.
I think it'll be back. And if you're a BB fan you better hope Ch 9 keeps it because TEN can't afford it so it'll be shelved indefinitely. If they're struggling to pay for their #1 show Offspring now that their government grants have ended, they sure as hell don't have the $ for BB.
