I’m the same, although I was hooked on Big Brother for a few series and I just could not tell you why. I even applied to go on Big Brother and got worrying close to being selected. I told this story on the old boards.
I think after I saw a Charlie Brooker thing where he showed just how pathetically easy it is to edit 24 hours of footage to make whoever they feel like look good / interesting / funny and the show runners can basically dictate. That, and my media studies teacher at sixth form going on a lengthy tirade about how ‘Driving School’ was all made up shite.
