I think he’ll be fine. I live alone and watch Jeopardy and Wheel of Fortune while eating dinner. Sort of ho-hum, but better that eating with just the cat.
BTW, people thought Jeopardy would die with out Alex Trebeck, but Ken Jennings turns out to be reasonably personable too.
IIRC, some people were really upset that Trebek took over for Art Fleming and said no one could ever replace Fleming.
Kan and Mayim are both excellent, in different ways.
