We're still getting to know the candidates, but one thing that was noticeable about their arrival was how slick their entrances seemed. Several put their carefully packed bags down to allow a proper camera pose for the paparazzi.
Those bags are constrained by very strict rules on what personal belongings they can bring into the house. All bags are checked and inventoried. And we've had some information from Davina about the contents of those bags - for example, one has packed about 30 pairs of knickers.
What we couldn't see, however, were the invisible bags each contestant brought with them - the bags which contain the things that really make Big Brother work and worth sticking with. And those contents aren't checked by anyone.
The writer Robert Bly maintains that we all own an invisible bag that grows and grows and that we drag around with us, essentially until it bursts. And the contents of the invisible bags? Every impulse or emotion that we've repressed from the age of about one or two. Feelings of anger, envy or sexuality considered inappropriate by our teachers, our culture, our friends, or our bosses. Every bit of unacceptable behaviour that you've ever curbed - it's all in there.
As we get older, the bag obviously becomes more and more stuffed. Sometimes we might decide to reopen it and reconnect with some of its contents. Eventually at some point, if we're not careful, the bag will burst.
BB8 is still compelling because it works in the same way as great dramas have for centuries, from King Lear to Apocalypse Now (and even Coronation Street). All are more or less based on what happens when the invisible bag bursts open.
Big Brother is a live example of seeing real people's bags burst open, under the pressure and scrutiny of the cameras. How well each individual copes is a big part of how popular they will become and whether they will win.
We like to see the bags burst, then we like a bit of dignity and grace in dealing with it.
