In terms of entertainment, I think positives trump negatives every time, that's why it's interesting seeing the conversations with people like James and Austin or Janice and some of the Brits. It's not just one dimensional bitching, it's sometimes quite interesting.
I like the psychology of the show. I like seeing how different people view things, and when we have US housemates on the show, that can be particularly interesting. That's why I like James as a housemate. I've seen him be inquisitive that way with people, it's the kind of thing I'd do if I were in there.
