Rating: None
Premise: The lives of disparate housemates are captured on-camera 24/7 over a three-month period, with one person getting the boot every week (originally it was every two weeks). The last to leave wins $500,000. The intrusive Orwellian premise drew its share of critical barbs, but the series was popular enough to spawn a number of sequels.
