: "Big Brother" instituted a new twist for Season 15 -- America got to vote for an MVP and that person got to secretly nominate a third person to be on the block next to the Head of Household's nominees.
Why this worked
: It freshened up a show by making the machinations more interesting each week and also sowing seeds of paranoia, since the MVP's identity was a secret. Unfortunately, having a ringer in the house did not let this twist see its full potential, but we're hoping a legitimately all-new cast next summer will let the MVP twist play out in a more organic way.
