"Reality Shows" all seem to follow the same format. Find a quirky hook, then script a season of shows . . . which you pretend are "real" and "unscripted" and hope there is enough market share to extend you another season. Just like the producers of the storage locker auction series, the producers "seed" a "treasure" in a storage locker (or in this case, a location of the island) for the cast to discover, then haul it off to an "expert" to opinie endlessly about the artifact which was found (right where the producer put it) on the set of the show, whoopie!
If you like this show stay away from three card monte and the lottery and you will be richer for it, at least this show isn't sucking money out of your pocket like three card monte and the lottery, making it at least a harmless distraction.
