I wish Alves luck, because it's a tough job — a host can make or break a show for its audience. There are the great emcees, like charming So You Think You Can Dance host Cat Deeley, and then there are the unmemorable, such as season one Top Chef host Katie Lee, who was quickly replaced by Padma (let's not even get started on Top Chef Masters' Kelly Choi). And then there's those who can end things before they begin — I'm considering not watching Launch My Line because the voices of hosts Dean and Dan Caten from DSquared are so grating on my ears.
So, dish: which TV show hosts are your favorites — and least favorites?
