It would almost appear that Jeopardy! seems to be coming to it's end. After they go out with this Quest thingy...what next? Then again...maybe a little change wouldn't be a bad idea, change it up a bit, then go back to the way it's been played for a while.
I don't think it's coming to its end -- this isn't the first time where they've had a "super" tournament. Count the ABC network version at least a decade ago and the Million-Dollar Masters tourney, and you have two tourneys -- all before Ken.
It's a stunt and nothing more. We'll see what happens.
I thought the b-plot was barely there for the first half, but then was the focus for the second. That was odd. Still, it did nothing for me, and like Big Bad said, seemed like a waste of Alyson Hannigan (and even Kristen Wiig).
