Sadly, human nature dictates that we do derive a certain pleasure from others' misfortunes - this concept after all is the lifeblood of any soap opera.
Real life situations however, are different, and I do find them unpleasant, regardless of how often the programme makers set themselves up as 'helpful' by offering counselling.
If the counselling was as good TV as the riows and fights, we would all watch that, but of course, the 'presentation problem' is the interesting bit.
I find my attitude is the same as boxing - I do watch, and to a degree I enjoy wathcing, but I am not happy with myself for doing either.
Similarly with both - I will watch if they are on, but I don't go out of my way to see either.
