Its not just that, I would care, but not when they're going, like:
Chris - "So, you've got a son with downs syndrome"
Contestant "Yes its very sad"
Chris "Right, next round..." 30 seconRAB
Chris "So, how do you cope?"
Contestant "It can be bad at times, yeah, but he's a good lad."
Chris "Yeah, well I would love you to win... NEXT ROUND!"
Its all too fast a format to allow you to grow to like a contestant and care about their problems. Just makes the gaps inbetween the questions more annoying than ever!
