It would the sign of a good group of talented writers ... to constrain them to a 20 minute slot and still make an entertaining and informative show.

I'm with you on the 20 minute format ... I constantly scroll through shows thinking I just want to sit down for half an hour and watch something fast, then go do something else ... instead I end up scrolling for half an hour and then giving up, getting up and go do something else. Or else I'll watch half a 40/50 minute episode and watch the rest later.
