It's still early, but the poll that we've put up at the top of the page (BTW, in case you didn't notice, there's a poll at the top of the page) has Drew's positives leading his negatives by about a 2 to 1 margin. I wonder if there's any other candidate, aside from an impossibility like Tom Bergeron, whose approval rating among us serious fans would have been as high.
Meanwhile, as has been said many times before, we're going to watch anyway. (Put more precisely, a change of host isn't likely to change our viewing habits. We'll still watch about as much as we ever did.) If CBS can find a name host who's willing to do it, who has a pre-sold everyman appeal and who's competent at first with the likelihood that he'll get better, I think they should count their blessings.
I also doubt that Drew's the type who'll want to come in and put his personal stamp on everything. My impression is he doesn't want to work that hard. Moreover, from what few quotes we've gotten, he seems to understand the value of the show the way it is now. I'm not saying there won't be changes, that would have happened with any host. I'm just saying that it's not likely he'll turn the show into Drew's Wacky Improv Pricing Game Show.
