Watching the BB 10 launch last night gave me a weird sense of déjà vu. Hadn't I seen these contestants last year? And the year before? In fact, hadn't I seen them every year without fail?

Which leads me to conclude there is a factory in Elmstree churning out the same quota of hideous stereotypes each year for the purpose of Big Brother. I can just see the production line:

3 or 4 'bombshells' with genetically enhanced body part and life ambition to date footballer. Check.

2 or 3 self appointed 'God's gift to the ladies' - extra dollop of arrogance. Check.

1 or 2 gorgeous, slightly dumb and unthreatening gay guys. Check.

1 loud and intensely annoying short girl to be loved and then vilified by the British public as she screeches her way through the next 13 weeks.
Check.

1 lesbian - must be of the skinhead/Mohican, loud-mouthed variety. Check.

A couple of older weirdos to get voted out in the first week and shunned by the others. Check.

God it's all so BORING. I kept waiting for someone genuinely interesting to appear - or at least someone who didn't say 'I don't give a toss what anyone thinks, me'. Surely in all the thousands of people who audition there must be someone out there who doesn't think their looks are 'ten out of ten' or that bitching is a life skill?

As usual the representation of women is dismal. They're either bitchy, stupid, vacuous or all of the above - apart from the gay ones, who are all loud, predatory and look like they lost a battle with a razor.

My heart actually sank when Davina told us we'd be watching some of this lot for the next 13 weeks. What's the point? We've seen it all before.

BB10...or 9... or even 8.
