Addressing something Jason said, chemistry with a consistent panel would have helped, but it seems like they had a healthy stable of celebs--Vicki, Edie McClurg, Marcia Wallace, Betty White, Khrystyne Haje, Brad Garrett, Ronn Lucas (and friend!), CNR, even people like Joe Alaskey, Bill Kirchenbauer, and Bruce Baum. (Sorry Jason, Bruce Baum is an acquired taste.)
To Brandon's points, having seen MG 7x/PM/syndicated reruns for over 3 decades is a bit much and a change of pace is welcome. Maybe my opinion is a case of recency bias. Maybe it's because the last time I remember MG 90 airing 5+ times a week for any decent period of time was on GSN in 2001-02.
Maybe it's due to some parts of the 70s version and Gene's schtick aging badly. Maybe it's me being glad to see a show that I got to see a handful of times, when there was no school, the alignment of the stars was just right, and the weather complied, and even then, reception on my B&W TV was, at best, meh.
Match-Up was enough of a deviation from the norm that it worked well within the format.
