I loved this movie! It was often times a hilarious parody of CBS's Survivor series. I should warn you that although the movie contains partial frontal nudity (bare breasts are revealed), it is fairly safe to watch.
The movie often teases on what if's, such as things that the contestants or the host wouldn't normally do, so the rules are often challenged. It is good clean sexual fun, even though there are no sex scenes involved. Lesbianism and a spanking are teased at.
I would definitely recommend this to any Survivor fan who hasn't seen it yet, but not to any kiddies.
