I've seen the show. IMO, I think this show creates drama and upsets people just to get ratings. If it's even real people who respond, which I doubt.
The stuff is so.... contrived. I can't stand it, personally. In fact, if it comes on without our realizing it, My Man will grab the remote, curse and turn off the TV. He detests it.
I think it is a very dangerous experiment in sociology that is done without consent of the people being upset. That is, if it isn't completely all actors, which is a pretty good guess of what is going on there. Some of the responses of people, in the few times I've watched it were SO pat and seemingly rehearsed, that I think the people who are supposed to "not know" it is a set up are simply part of the cast.
