I think you're spot on there (apart from the torturing the viewers bit), although wouldn't be surprised if some of the contestants were 'ordered' to up the hystrionics a bit by the production staff in order to keep in line with what they want, and an easier pass through. Would be good to see a suttle, genuine piss-taker slip under the radar in the future and make it through to lives, and treat the show in the context it should be. Older contestant could be good candidate to try that.
