The Winter Couples.
The only Big Brother season to air in winter, slotted into CBS's lineup during the 2008 writer's strike. Sixteen houseguests move in and are paired into couples on Day One — "'Til Death Do You Part" built out as a structural premise. The off-season slot shows. The casting feels rushed, the chemistry uneven, and the twist constrains the game more than it opens it. A historical curiosity more than a rewatch, the run that earned the show its summer-only future.
