People hate reality TV, because it's cheap, plastic, throw away viewing. It provides little in the way of real entertainment. I mean take an average BB episode. If you edit out all the sitting around, in an hour show I doubt you would have more than 3 minutes of real pay attention stuff? If that was a film at the cinema, you would have walked out and gone for a pint!
It is also loathed by people like me because it is a misnomer to call it reality TV. It is anything but reality! How can it be reality, when BB is full of hand picked freaks who all know they are on camera and will do anything to get noticed. The worst thing I can do is encourage them by watching!
That's just my opinion and I realise we are all different which is cool. That's what the remote control is for I guess!
