Of all the reality shows I like Survivor the best. They drop 20 or so people off a remote island and these people have to not only forage food, build makeshift camps but do daily group physical tasks. Whichever group wins is immune from eviction and the losing group has to evict one person off. After sometime the group tasks cease and individuals have to either win immunity tasks or risk eviction from the remaining safe members.
In the end the evicted housemates and not the audience decide who wins Survivor, so it truly is a test of physical and social skills plus can you survive on bare minimum food. If you have Netflix they have 2 seasons on it. This will be the 44th season of Survivor .
