I think we had a version of Survivor here under the franchise of the original show. It's a good show regarding the tips and tricks of surviving. However, it was noticeable that the show was capitalizing on the indifference and spats among the contestants. And nearing the end of the contest, it was like a rat race that friendship was forgotten.
I think the survival shows which unfold outdoors, are a lot better than the reality shows that unfold indoors. It seems most of those shows just have people drinking, gossiping, fighting and making fools of themselves. While the former, really pushes people to limits they never knew or suspected they could reach.
