Its money, UK tv has no money at the moment. BBC are under pressure to give some of the licence fee to ITV because ITV are on the verge of going bust. So expensive drama on the BBC is under pressure. I suspect Torchwood is going so that Who can continue.

Though personally I think the BBC should hack eastenders back to 1 or 2 episodes a week, because thats a vast money sink.

But yes, you're right. The fans who were in Torchwood for the boyslash are desperately upset and hating RTD at the moment, while everybody else loved CoE.
