Light-hearted, in case it wasn't obvious, but it seems that every quiz show I watch lately has ridiculous amounts of filler. Repeatedly explaining how the game works, or reciting each contestant's points total even though they're clearly visible to us, and in some cases even going over the basic maths each time.
'Jane has 20 points and Mary has 50 points. That puts Jane 30 points behind!' and suchlike - especially if it's done before the ad break and then again after it. It annoys me so much that I can't watch.
And don't get me started on any kind of competition-based show that announces 'the winner is...' and then pauses for 20 seconds. It's not suspense. 2 seconds of pausing is suspenseful. 20 is extremely irritating.
The only quiz show I've found not to be guilty of any of this is University Challenge, which I enjoy even though it makes me feel very ignorant for only guessing a half-dozen right answers most of the time.
Eh. It's late and I'm feeling curmudgeonly. What do you all think?
