Ken Jennings proved this week he should be Alex Trebek's successor as Jeopardy! host

The Daily Beast

Jennings was "perfectly fine" as the first interim host of the post-Trebek era, says Kevin Fallon. "For those of us reeling and skeptical in the wake of Trebek’s absence, that’s a ringing endorsement. He basically is doing an approximation of Alex. He’s not yet as articulate, nimble or effortless. He’s starting to pepper in those Trebekisms, little asides and explanations for why things were wrong. But he’s still missing the ease. How can you be authoritative and wily at once? It’s why the word singular exists, and why it’s used to describe Alex. Jennings needs to be more present. He’s nervous! It’s understandable, and there’s a learning curve that should be allowed to get over that."
