I had some misgivings when I heard he'd be the host of Millionaire, after Merideth Viera resigned to get her one-hour daytime talk show ready for next fall. She was a very good host, smart as well as personable, and she won a Daytime Emmy for her hosting.
I don't like Cedric as much. After all, you have to be really smart to answer these questions. And as the host, he doesn't impress me as someone who's really a learned man. I realize as a comedian and actor, he has a character he must portray. I'm also not thrilled with the hat, although again, that's part of his character.
So over time, he's grown on me. I still am not ready to say he's the ideal replacement. But these days smart quiz shows are at a premium... only Jeopardy and Millionaire. So if he can capture a segment of the audience that might not otherwise watch Millionaire and keep the ratings high enough for renewal, he's fine by me. BTW, I won $16,000 on the show about 5 years ago. Viera was very cordial to me during the breaks.
