Sad News, RIP Alex. Hadn't heard that he stopped filming but see now his last show was recorded 10/28.
I like your reboot ideas. Also, maybe a month's break would help with the transition. The last episode with Trebek airs in December, and if they jump right into the new host, it will be jarring.I think a new host would necessitate a mild reboot. Not the game itself, but just enough changes in the look & feel so that every moment isn’t a reminder of Trebek’s absence. Change the color scheme, flip the left/right orientation, juggle the contestant interview segment, whatever.
If they don’t want to do that, then Kennings moves up on the list. He’s the only candidate who really “belongs” to the existing show. He has his own Jeopardy shoes and doesn’t have to fill Alex’s.
Watching the next few weeks will be very bittersweet. RIP.
