Absolutely. I think Elizabeth has hit the nail right on the head.
Despite this year's housemates' outward shows of affection towards each other, I don't think any one of them has any genuine affection for anyone else.
The amount of bitching and backbiting in the first week has been incredible and terrible to watch. I feel that everyone is looking after number one, trying to fool the public into seeing how caring and concerned they are, but actually they couldn't give a damn about the rest.
Just my opinion.
