Last night marked the Season 2 premiere of this fast-moving quiz show, with Jeopardy! Champ Ken Jennings as the season’s first contestant (pictured), trying to answer 500 questions without giving three wrong answers in a row. Imagine how surprised Jennings was, not to mention ABC, when he was eliminated after a total of four questions. Yikes. It’s an entertaining game, and a game in which a contestant’s age, or youth, can be either an asset or a definite liability. Tonight: More contestants, but no more Ken Jennings.
