Nah, that series, when Cameron won, was just mainly dull. It came after series three with Jade and think they were trying to damp it all down a bit after the criticism that got, but there’s a reason series five ramped up the craziness again. The first series, when the participants had no idea how popular it was, is the only one that was really much of a study in how people trapped in a house together behave without manipulation.
A friend of mine went into a different reality show not long after BB first got big, but no one cared about it, and instead of leaving to massive hoohah he emerged to find that pretty much no one but the contestants’ families had watched: I only bothered with a couple of episodes.
