Re: MG/HS Hour, this would have been a better show with just one host. To go from the madcap energy of Gene to Jon, who's basically playing it straight and didn't really have Gene's comedic flair, back to Gene, is really jarring.
Also to have Jon on the Match Game panel every single day... they really could have used his seat for another rotating celebrity.
They also could have paid more respect to the historic format of Hollywood Squares, adding a secret square, etc.
All in all, NBC might have been better off just trying to revive Match Game with Gene in 1983. It might have worked. Here we are, 35 years later, and that's the main reason most people are watching these episodes anyway, the Match Game portion.
It's sort of sad that this was the last iteration of Gene Rayburn's Match Game; that really was his show.
