At this point there's no defending why we continue to watch Big Brother. The show reliably casts some of the most irritating people in reality TV, it airs multiple times a week, it lasts forever, and more often than not, the winner is a disappointment. Yet, the new season starts tonight, and that's where we'll be. We'll be there for the Zingbot, and for all of the new rules. We'll be there for the Head of Household competitions, the increasingly Byzantine twists, and the challenges (last year they had someone compete as a robot for a week). This year's 16 new players include a Broadway dancer, a plus-size model, a 53-year-old petroleum engineer (ancient by the show's standards), and a "wine safari guide" (who should prove popular in the Big Brother house).
