A True TV Gem!
30 August 2001 | by (United States) – See all my reviews

Watching reruns of the original What's My Line on the Game Show Network (which has just cancelled its "Black & White Sunday Night," much to my dismay) reminds me of what is missing in today's entertainment: Genuine wit and intelligence. The celebrity participants in this and other "early TV" panel shows simply sparkle in a natural way that is rarely if ever seen in today's world of airbrushed, stage-managed "images." There's an innocence, too, that could never be duplicated 40+ years beyond the heyday of these shows. It's really sad these programs can't find appreciation among a new audience, but perhaps the very qualities that seem so appealing are what hinder that. I hope some day this version of this show gets another chance to captivate audiences the way it captivates me.
