Perhaps that's why Jim Lange never hosted a GT game show.
It could also have been that he wasn't a great host. Pat Finn, same reason.
I disagree with you on that one. I think Pat is a decent host, it's just the shows he was given. TJW 90, for me, didn't really work until they added elements from the original TJW. Okay, they didn't change the "game of definitions" format, but in terms of the game play, I'd rather see categories and Jokers on the slot machine instead of dollar amounts in the main game. Shop Til You Drop was a hokey show, and sometimes reeked of a TPIR wannabe, but it was on the air off and on for a while. The show had three sidekicks/announcers over the years. The first of course was Mark L Walburg, who would later have hits and misses with other game shows, then Jason Grant Smith, who I thought was the best fit for the series, then Dee Bradley Baker... talented voice artist, annoying as the sidekick IMO. I had said a long time ago that both Dee Baker and Jay Stewart dressed up in silly costumes, but the biggest difference was that when Jay did it, the show's dignity remained intact.
Jim Lange was discussed on here many times. I thought he was at least tolerable. Bullseye was a great format, but moved a little slow, and it was no better with the celebs. I thought he was decent on Name That Tune, but the contestant pool tended to have very showy contestants that were overboard on personality as well as lacking in good sportsmanship. With The Dating Game, all he had to do was introduce the contestants and the rest of the game ran itself with Jim on the sidelines, almost never saying a word. Give and Take and Spinoffs were both forgettable, being games of luck with formats that weren't enduring enough for a long running series. Oh My Word and Take my Word for It were also "meh", and likely inspired Wordplay, which was also kinda "meh." I liked Triple Threat, but the game came along when game shows were starting to wane.
I think it's just that sometimes decent hosts were given formats that just didn't work, with no real fault of their own. Art James is a good example. Art was great on Say When! and The Who, What or Where Game, but everything else just came and went. The Magnificent Marble Machine had the world's largest pinball machine, but beyond that the main game was just your average crossword puzzle type clue game, and sometimes, watching people play pinball just isn't exciting, despite the size of the machine. Blank Check (which the crew called "Blank Mind") was a dumb "guess the number I'm holding" game. Pay Cards and Super Pay Cards might be good for a few shows, but it's not a compelling enough format for a long running series. Catch Phrase, IMO was a game that should've had a longer run, and of course overseas, it did have a longer run. I just think that perhaps the game was a little ahead of its time, and also, I think Art's understated style of hosting was perhaps a bit bland for 80s audiences.
