No, though I'm mainly basing that on his early years and the fact that Bob Barker basically IS The Price is Right to me (and yes, I'm aware he wasn't the first host either). I haven't watched the show in like 15 years, so I have no idea if he's vastly and dramatically improved since the beginning, or if he's basically more or less the same and I'd still dislike him.
Also for the record, I hate the idea of a Let's Make a Deal without Monty Hall, a Jeopardy without Alex Trebek, or a Wheel of Fortune without Pat Sajak.
I'm also willing to take that even farther and say that they should never do The Newlywed Game or Card Sharks without Bob Eubanks, Press Your Luck without Peter Tomarken, Who Wants to Be a Millionaire without Regis Philbin, or Double Dare without Marc Summers. There's probably a few others I'd have strong opinions about (I used to watch a LOT of game shows as a kid), but most of them are probably too obscure for most people here (do any of you even know who Wink Martindale or Jim Ward even are?).
Some hosts just become so iconic - even if they weren't the original host of their show - that it almost feels like sacrilege to do it without them.
Plus, you know, it would be nice to see people come up with actual NEW shows rather than just rehashing the same old shit until the end of time.
