People need a good guy and a bad guy.

Years of formulaic american movies has conditioned us to expect this classic set up.

It's in movies, soap operas, even the news! and BB is no exception.

The BB crowd - now more than ever - need someone to chant out each week.

This year it has been Pauline, Toya, Helen, Ashleigh, Danielle, Steven and Mark who have all been in the firing line for the role of 'bad guy' at some point.

And having identified the bad guy - we then look around for 'the hero'.

Right now - Helen gets the 'bad guy' badge (aided by the BB tasks and edit) and Ashleigh has been given the 'good guy' badge. Even though a few weeks ago (after her 'evil plan' - Ashleigh was the bad guy)

People then pour all their years worth of 'bad guy' emotions onto the current figure of 'bad guy' - hence we are now at the stage of people mentioning Hitler in the same breath as Helen on forums!

People also excuse and ignore the bad traits of 'good guy' as they want their hero to be whiter than white as the good v bad scenario is played out before us.

I have no doubt at all that if Helen had been evicted 6 weeks ago - there would be someone else in there right now filling the role of 'bad guy'. Probably Ashleigh or Chris.

It's kind of unfair on the HMs who are pawns in the BB game of good v bad, but after 15 years on the screen - it's no surprise really.

It began with Nick v Craig in series 1 and kept on rolling..
