I always laugh a bit at the idea anyone is trained to be a game show host. Bob Barker was a broadcaster, a type of performer to be sure, and he happened to land a gig hosting a game show, which then led to Price. It's not like there's a game show hosting major in college--people come at it from different performance backgrounds, be it radio to TV or talk shows or what have you. Sure, now you have Drew and Howie coming from a comedic background (as was the great Ray Combs with Feud), and you have Meredith from a journalistic background.
Price faced a daunting challenge. Stick too close to the Barker style and risk the "trying to copy Bob" complaints, or give it a freshened--not completely different--identity and risk the "not enough like Bob" complaints. Damned if you do....
For all the complaints about it being so radically different, it's still pricing games on a flashy set with three doors, the same theme song (HORRORS, though, they updated some of the music cues!), with the same basic structure. The set got minor updates, the music got minor updates, and the host is using his style, much as Barker (and Bill Cullen before him) used his personal style. Perfect? Eh, nothing is. But hardly a vast departure from the show as it's been known all these years.
