i've participated in a reality show of similar design. what the sis-in-law says is true. it's not scripted but themes are thought out and the "actors" are prompted by the film crew, etc. some stuff is totally fictional. unfortunately, there are lots of unsuspecting victims of these type shows as well. lots of good, well-intentioned people get robbed with empty promises from the people running the show.
Anyone ever notice that KS does that weird eye flutter thing that Jennifer Love Hewett does?
